+ * The device works as an standard CDC device, it has 2 interfaces, the first
+ * one is for firmware access and the second is the serial one.
+ * The protocol is very simply, there are two possibilities reading or writing.
+ * When writing the first urb must have a Header that starts with 0x20 0x29 the
+ * next two bytes must say how much data will be sent.
+ * When reading the process is almost equal except that the header starts with
+ * 0x00 0x20.
+ *
+ * The device simply need some stuff to understand data coming from the usb
+ * buffer: The First and Second byte is used for a Header, the Third and Fourth
+ * tells the device the amount of information the package holds.
+ * Packages are 60 bytes long Header Stuff.
+ * When writing to the device the first two bytes of the header are 0x20 0x29
+ * When reading the bytes are 0x00 0x20, or 0x00 0x10, there is an strange
+ * situation, when too much data arrives to the device because it sends the data
+ * but with out the header. I will use a simply hack to override this situation,
+ * if there is data coming that does not contain any header, then that is data
+ * that must go directly to the tty, as there is no documentation about if there
+ * is any other control code, I will simply check for the first
+ * one.
+ *
+ * I have taken some info from a Greg Kroah-Hartman article:
+ * http://www.linuxjournal.com/article/6573
+ * And from Linux Device Driver Kit CD, which is a great work, the authors taken
+ * the work to recompile lots of information an knowledge in drivers development
+ * and made it all available inside a cd.

+/*
+ * The following describes what I learned from studying the old
+ * ark3116.c driver, disassembling the windows driver, and some lucky
+ * guesses. Since I do not have any datasheet or other
+ * documentation, inaccuracies are almost guaranteed.
+ *
+ * Some specs for the ARK3116 can be found here:
+ * http://web.archive.org/web/20060318000438/
+ * www.arkmicro.com/en/products/view.php?id=10
+ * On that page, 2 GPIO pins are mentioned: I assume these are the
+ * OUT1 and OUT2 pins of the UART, so I added support for those
+ * through the MCR. Since the pins are not available on my hardware,
+ * I could not verify this.
+ * Also, it states there is "on-chip hardware flow control". I have
+ * discovered how to enable that. Unfortunately, I do not know how to
+ * enable XON/XOFF (software) flow control, which would need support
+ * from the chip as well to work. Because of the wording on the web
+ * page there is a real possibility the chip simply does not support
+ * software flow control.
+ *
+ * I got my ark3116 as part of a mobile phone adapter cable. On the
+ * PCB, the following numbered contacts are present:
+ *
+ * 1:- +5V
+ * 2:o DTR
+ * 3:i RX
+ * 4:i DCD
+ * 5:o RTS
+ * 6:o TX
+ * 7:i RI
+ * 8:i DSR
+ * 10:- 0V
+ * 11:i CTS
+ *
+ * On my chip, all signals seem to be 3.3V, but 5V tolerant. But that
+ * may be different for the one you have ;-).
+ *
+ * The windows driver limits the registers to 0-F, so I assume there
+ * are actually 16 present on the device.
+ *
+ * On an UART interrupt, 4 bytes of data come in on the interrupt
+ * endpoint. The bytes are 0xe8 IIR LSR MSR.
+ *
+ * The baudrate seems to be generated from the 12MHz crystal, using
+ * 4-times subsampling. So quot=12e6/(4*baud). Also see description
+ * of register E.
+ *
+ * Registers 0-7:
+ * These seem to be the same as for a regular 16450. The FCR is set
+ * to UART_FCR_DMA_SELECT (0x8), I guess to enable transfers between
+ * the UART and the USB bridge/DMA engine.
+ *
+ * Register 8:
+ * By trial and error, I found out that bit 0 enables hardware CTS,
+ * stopping TX when CTS is +5V. Bit 1 does the same for RTS, making
+ * RTS +5V when the 3116 cannot transfer the data to the USB bus
+ * (verified by disabling the reading URB). Note that as far as I can
+ * tell, the windows driver does NOT use this, so there might be some
+ * hardware bug or something.
+ *
+ * According to a patch provided here
+ * (http://lkml.org/lkml/2009/7/26/56), the ARK3116 can also be used
+ * as an IrDA dongle. Since I do not have such a thing, I could not
+ * investigate that aspect. However, I can speculate ;-).
+ *
+ * - IrDA encodes data differently than RS232. Most likely, one of
+ * the bits in registers 9..E enables the IR ENDEC (encoder/decoder).
+ * - Depending on the IR transceiver, the input and output need to be
+ * inverted, so there are probably bits for that as well.
+ * - IrDA is half-duplex, so there should be a bit for selecting that.
+ *
+ * This still leaves at least two registers unaccounted for. Perhaps
+ * The chip can do XON/XOFF or CRC in HW?
+ *
+ * Register 9:
+ * Set to 0x00 for IrDA, when the baudrate is initialised.
+ *
+ * Register A:
+ * Set to 0x01 for IrDA, at init.
+ *
+ * Register B:
+ * Set to 0x01 for IrDA, 0x00 for RS232, at init.
+ *
+ * Register C:
+ * Set to 00 for IrDA, at init.
+ *
+ * Register D:
+ * Set to 0x41 for IrDA, at init.
+ *
+ * Register E:
+ * Somekind of baudrate override. The windows driver seems to set
+ * this to 0x00 for normal baudrates, 0x01 for 460800, 0x02 for 921600.
+ * Since 460800 and 921600 cannot be obtained by dividing 3MHz by an integer,
+ * it could be somekind of subdivisor thingy.
+ * However,it does not seem to do anything: selecting 921600 (divisor 3,
+ * reg E=2), still gets 1 MHz. I also checked if registers 9, C or F would
+ * work, but they don't.
+ *
+ * Register F: unknown

+ * wValue: BaudDivisor value - see below
+ * wIndex: Port
+ * wLength: 0
+ * Data: None
+ * The BaudDivisor values are calculated as follows:
+ * - BaseClock is either 12000000 or 48000000 depending on the device.
+ * FIXME: I wish I knew how to detect old chips to select proper base clock!
+ * - BaudDivisor is a fixed point number encoded in a funny way.
+ * (--WRONG WAY OF THINKING--)
+ * BaudDivisor is a fixed point number encoded with following bit weighs:
+ * (-2)(-1)(13..0). It is a radical with a denominator of 4, so values
+ * end with 0.0 (00...), 0.25 (10...), 0.5 (01...), and 0.75 (11...).
+ * (--THE REALITY--)
+ * The both-bits-set has quite different meaning from 0.75 - the chip
+ * designers have decided it to mean 0.125 instead of 0.75.
+ * This info looked up in FTDI application note "FT8U232 DEVICES \ Data Rates
+ * and Flow Control Consideration for USB to RS232".
+ * - BaudDivisor = (BaseClock / 16) / BaudRate, where the (=) operation should
+ * automagically re-encode the resulting value to take fractions into
+ * consideration.
+ * As all values are integers, some bit twiddling is in order:
+ * BaudDivisor = (BaseClock / 16 / BaudRate) |
+ * (((BaseClock / 2 / BaudRate) & 4) ? 0x4000 // 0.5
+ * : ((BaseClock / 2 / BaudRate) & 2) ? 0x8000 // 0.25
+ * : ((BaseClock / 2 / BaudRate) & 1) ? 0xc000 // 0.125
+ * : 0)
+ *
+ * For the FT232BM, a 17th divisor bit was introduced to encode the multiples
+ * of 0.125 missing from the FT8U232AM. Bits 16 to 14 are coded as follows
+ * (the first four codes are the same as for the FT8U232AM, where bit 16 is
+ * always 0):
+ * 000 - add .000 to divisor
+ * 001 - add .500 to divisor
+ * 010 - add .250 to divisor
+ * 011 - add .125 to divisor
+ * 100 - add .375 to divisor
+ * 101 - add .625 to divisor
+ * 110 - add .750 to divisor
+ * 111 - add .875 to divisor
+ * Bits 15 to 0 of the 17-bit divisor are placed in the urb value. Bit 16 is
+ * placed in bit 0 of the urb index.
+ *
+ * Note that there are a couple of special cases to support the highest baud
+ * rates. If the calculated divisor value is 1, this needs to be replaced with
+ * 0. Additionally for the FT232BM, if the calculated divisor value is 0x4001
+ * (1.5), this needs to be replaced with 0x0001 (1) (but this divisor value is
+ * not supported by the FT8U232AM).

+
+The data to and from all ports on the peripheral is multiplexed
+through a single endpoint pair (EP1 since it supports 64-byte
+MaxPacketSize). Therefore, the data, commands, and status for
+each port must be preceded by a short header identifying the
+destination port. The header also identifies the bytes that follow
+as data or as command/status info.
+
+Header format, first byte:
+
+ CLLLLPPP
+ --------
+ | | |------ Port Number: 0-7
+ | |--------- Length: MSB bits of length
+ |----------- Data/Command: 0 = Data header
+ 1 = Cmd / Status (Cmd if OUT, Status if IN)
+
+This gives 2 possible formats:
+
+
+ Data header: 0LLLLPPP LLLLLLLL
+ ============
+
+ Where (LLLL,LLLLLLL) is 12-bit length of data that follows for
+ port number (PPP). The length is 0-based (0-FFF means 0-4095
+ bytes). The ~4K limit allows the host driver (which deals in
+ transfer requests instead of individual packets) to write a
+ large chunk of data in a single request. Note, however, that
+ the length must always be <= the current TxCredits for a given
+ port due to buffering limitations on the peripheral.
+
+
+ Cmd/Status header: 1ccccPPP [ CCCCCCCC, Params ]...
+ ==================
+
+ Where (cccc) or (cccc,CCCCCCCC) is the cmd or status identifier.
+ Frequently-used values are encoded as (cccc), longer ones using
+ (cccc,CCCCCCCC). Subsequent bytes are optional parameters and are
+ specific to the cmd or status code. This may include a length
+ for command and status codes that need variable-length parameters.
+
+
+In addition, we use another interrupt pipe (endpoint) which the host polls
+periodically for flow control information. The peripheral, when there has
+been a change, sends the following 10-byte packet:
+
+ RRRRRRRRRRRRRRRR
+ T0T0T0T0T0T0T0T0
+ T1T1T1T1T1T1T1T1
+ T2T2T2T2T2T2T2T2
+ T3T3T3T3T3T3T3T3
+
+The first field is the 16-bit RxBytesAvail field, which indicates the
+number of bytes which may be read by the host from EP1. This is necessary:
+(a) because OSR2.1 has a bug which causes data loss if the peripheral returns
+fewer bytes than the host expects to read, and (b) because, on Microsoft
+platforms at least, an outstanding read posted on EP1 consumes about 35% of
+the CPU just polling the device for data.
+
+The next 4 fields are the 16-bit TxCredits for each port, which indicate how
+many bytes the host is allowed to send on EP1 for transmit to a given port.
+After an OPEN_PORT command, the Edgeport sends the initial TxCredits for that
+port.
+
+All 16-bit fields are sent in little-endian (Intel) format.

+// sending XOFF in order to fix broken
+// systems that interpret the next

+// IOSP_CMD_SET_XON_CHAR
+//
+// Sets the character which Edgeport transmits/interprets as XON.
+// Note: This command MUST be sent before sending a SET_RX_FLOW or

+// This command is used to assist in the implementation of the

+// This IOSP command tries to place a marker at the end of the RX
+// queue in the Edgeport. If the Edgeport RX queue is full then
+// the Check will be discarded.
+// It is up to the device driver to timeout waiting for the
+// RX_CHECK_RSP. If a RX_CHECK_RSP is received, the driver is
+// sure that all data has been received from the edgeport and
+// may now purge any internal RX buffers.
+// Note tat the sequence numbers may be used to detect lost
+// CHECK_REQs.

+ *
+ * Nobody provided any proprietary information that was not already

+
+ This driver has been put together with the support of Innosys, Inc.
+ and Keyspan, Inc the manufacturers of the Keyspan USB-serial products.
+ Thanks Guys :)
+
+ Thanks to Paulus for miscellaneous tidy ups, some largish chunks
+ of much nicer and/or completely new code and (perhaps most uniquely)
+ having the patience to sit down and explain why and where he'd changed
+ stuff.
+
+ Tip 'o the hat to IBM (and previously Linuxcare :) for supporting

+
+ Third revision: USA28X version (aka USA26)
+
+ Buffer formats for RX/TX data messages are not defined by
+ a structure, but are described here:
+
+ USB OUT (host -> USAxx, transmit) messages contain a
+ REQUEST_ACK indicator (set to 0xff to request an ACK at the
+ completion of transmit; 0x00 otherwise), followed by data:
+
+ RQSTACK DAT DAT DAT ...
+
+ with a total data length of 63.
+
+ USB IN (USAxx -> host, receive) messages begin with a status
+ byte in which the 0x80 bit is either:
+
+ (a) 0x80 bit clear
+ indicates that the bytes following it are all data
+ bytes:
+
+ STAT DATA DATA DATA DATA DATA ...
+
+ for a total of up to 63 DATA bytes,
+
+ or:
+
+ (b) 0x80 bit set
+ indicates that the bytes following alternate data and
+ status bytes:
+
+ STAT DATA STAT DATA STAT DATA STAT DATA ...
+
+ for a total of up to 32 DATA bytes.
+
+ The valid bits in the STAT bytes are:
+
+ OVERRUN 0x02
+ PARITY 0x04
+ FRAMING 0x08
+ BREAK 0x10
+
+ Notes:
+
+ (1) The OVERRUN bit can appear in either (a) or (b) format
+ messages, but the but the PARITY/FRAMING/BREAK bits
+ only appear in (b) format messages.
+ (2) For the host to determine the exact point at which the
+ overrun occurred (to identify the point in the data
+ stream at which the data was lost), it needs to count
+ 128 characters, starting at the first character of the
+ message in which OVERRUN was reported; the lost character(s)
+ would have been received between the 128th and 129th
+ characters.
+ (3) An RX data message in which the first byte has 0x80 clear
+ serves as a "break off" indicator.
+
+ revision history:

+ (for USA28X, see usa26msg.h)
+
+ Buffer formats for RX/TX data messages are not defined by

+
+ USB OUT (host -> USA28, transmit) messages contain a
+ REQUEST_ACK indicator (set to 0xff to request an ACK at the
+ completion of transmit; 0x00 otherwise), followed by data.
+ If the port is configured for parity, the data will be an
+ alternating string of parity and data bytes, so the message
+ format will be:
+
+ RQSTACK PAR DAT PAR DAT ...
+
+ so the maximum length is 63 bytes (1 + 62, or 31 data bytes);
+ always an odd number for the total message length.
+
+ If there is no parity, the format is simply:
+
+ RQSTACK DAT DAT DAT ...
+
+ with a total data length of 63.
+
+ USB IN (USA28 -> host, receive) messages contain data and parity
+ if parity is configred, thusly:
+
+ DAT PAR DAT PAR DAT PAR ...
+
+ for a total of 32 data bytes;
+
+ If parity is not configured, the format is:
+
+ DAT DAT DAT ...
+
+ for a total of 64 data bytes.
+
+ In the TX messages (USB OUT), the 0x01 bit of the PARity byte is
+ the parity bit. In the RX messages (USB IN), the PARity byte is
+ the content of the 8051's status register; the parity bit
+ (RX_PARITY_BIT) is the 0x04 bit.

+ 4th revision: USA49W version
+
+ Buffer formats for RX/TX data messages are not defined by
+ a structure, but are described here:
+
+ USB OUT (host -> USAxx, transmit) messages contain a
+ REQUEST_ACK indicator (set to 0xff to request an ACK at the
+ completion of transmit; 0x00 otherwise), followed by data:
+
+ RQSTACK DAT DAT DAT ...
+
+ with a total data length of 63.
+
+ USB IN (USAxx -> host, receive) messages begin with a status
+ byte in which the 0x80 bit is either:
+
+ (a) 0x80 bit clear
+ indicates that the bytes following it are all data
+ bytes:
+
+ STAT DATA DATA DATA DATA DATA ...
+
+ for a total of up to 63 DATA bytes,
+
+ or:
+
+ (b) 0x80 bit set
+ indiates that the bytes following alternate data and
+ status bytes:
+
+ STAT DATA STAT DATA STAT DATA STAT DATA ...
+
+ for a total of up to 32 DATA bytes.
+
+ The valid bits in the STAT bytes are:
+
+ OVERRUN 0x02
+ PARITY 0x04
+ FRAMING 0x08
+ BREAK 0x10
+
+ Notes:
+
+ (1) The OVERRUN bit can appear in either (a) or (b) format
+ messages, but the but the PARITY/FRAMING/BREAK bits
+ only appear in (b) format messages.
+ (2) For the host to determine the exact point at which the
+ overrun occurred (to identify the point in the data
+ stream at which the data was lost), it needs to count
+ 128 characters, starting at the first character of the
+ message in which OVERRUN was reported; the lost character(s)
+ would have been received between the 128th and 129th
+ characters.
+ (3) An RX data message in which the first byte has 0x80 clear
+ serves as a "break off" indicator.
+ (4) a control message specifying disablePort will be answered
+ with a status message, but no further status will be sent
+ until a control messages with enablePort is sent

+ Fourth revision: This message format supports the USA28XG
+
+ Buffer formats for RX/TX data messages are not defined by
+ a structure, but are described here:
+
+ USB OUT (host -> USAxx, transmit) messages contain a
+ REQUEST_ACK indicator (set to 0xff to request an ACK at the
+ completion of transmit; 0x00 otherwise), followed by data:
+
+ RQSTACK DAT DAT DAT ...
+
+ with a total data length of up to 63.
+
+ USB IN (USAxx -> host, receive) messages begin with a status
+ byte in which the 0x80 bit is either:
+
+ (a) 0x80 bit clear
+ indicates that the bytes following it are all data
+ bytes:
+
+ STAT DATA DATA DATA DATA DATA ...
+
+ for a total of up to 63 DATA bytes,
+
+ or:
+
+ (b) 0x80 bit set
+ indiates that the bytes following alternate data and
+ status bytes:
+
+ STAT DATA STAT DATA STAT DATA STAT DATA ...
+
+ for a total of up to 32 DATA bytes.
+
+ The valid bits in the STAT bytes are:
+
+ OVERRUN 0x02
+ PARITY 0x04
+ FRAMING 0x08
+ BREAK 0x10
+
+ Notes:
+
+ (1) The OVERRUN bit can appear in either (a) or (b) format
+ messages, but the but the PARITY/FRAMING/BREAK bits
+ only appear in (b) format messages.
+ (2) For the host to determine the exact point at which the
+ overrun occurred (to identify the point in the data
+ stream at which the data was lost), it needs to count
+ 128 characters, starting at the first character of the
+ message in which OVERRUN was reported; the lost character(s)
+ would have been received between the 128th and 129th
+ characters.
+ (3) An RX data message in which the first byte has 0x80 clear
+ serves as a "break off" indicator.

+ * Technical Specification reverse engineered with SniffUSB on Windows98
+ * =====================================================================
+ *
+ * The technical details of the device have been acquired be using "SniffUSB"
+ * and the vendor-supplied device driver (version 2.3A) under Windows98. To
+ * identify the USB vendor-specific requests and to assign them to terminal
+ * settings (flow control, baud rate, etc.) the program "SerialSettings" from
+ * William G. Greathouse has been proven to be very useful. I also used the
+ * Win98 "HyperTerminal" and "usb-robot" on Linux for testing. The results and
+ * observations are summarized below:
+ *
+ * The USB requests seem to be directly mapped to the registers of a 8250,
+ * 16450 or 16550 UART. The FreeBSD handbook (appendix F.4 "Input/Output
+ * devices") contains a comprehensive description of UARTs and its registers.
+ * The bit descriptions are actually taken from there.
+ *
+ *
+ * Baud rate (divisor)
+ * -------------------
+ *
+ * BmRequestType: 0x40 (0100 0000B)
+ * bRequest: 0x05
+ * wValue: 0x0000
+ * wIndex: 0x0000
+ * wLength: 0x0004
+ * Data: divisor = 115200 / baud_rate
+ *
+ * SniffUSB observations (Nov 2003): Contrary to the 'wLength' value of 4
+ * shown above, observations with a Belkin F5U109 adapter, using the
+ * MCT-supplied Windows98 driver (U2SPORT.VXD, "File version: 1.21P.0104 for
+ * Win98/Me"), show this request has a length of 1 byte, presumably because
+ * of the fact that the Belkin adapter and the 'Sitecom U232-P25' adapter
+ * use a baud-rate code instead of a conventional RS-232 baud rate divisor.
+ * The current source code for this driver does not reflect this fact, but
+ * the driver works fine with this adapter/driver combination nonetheless.
+ *
+ *
+ * Line Control Register (LCR)
+ * ---------------------------
+ *
+ * BmRequestType: 0x40 (0100 0000B) 0xc0 (1100 0000B)
+ * bRequest: 0x07 0x06
+ * wValue: 0x0000
+ * wIndex: 0x0000
+ * wLength: 0x0001
+ * Data: LCR (see below)
+ *
+ * Bit 7: Divisor Latch Access Bit (DLAB). When set, access to the data
+ * transmit/receive register (THR/RBR) and the Interrupt Enable Register
+ * (IER) is disabled. Any access to these ports is now redirected to the
+ * Divisor Latch Registers. Setting this bit, loading the Divisor
+ * Registers, and clearing DLAB should be done with interrupts disabled.
+ * Bit 6: Set Break. When set to "1", the transmitter begins to transmit
+ * continuous Spacing until this bit is set to "0". This overrides any
+ * bits of characters that are being transmitted.
+ * Bit 5: Stick Parity. When parity is enabled, setting this bit causes parity
+ * to always be "1" or "0", based on the value of Bit 4.
+ * Bit 4: Even Parity Select (EPS). When parity is enabled and Bit 5 is "0",
+ * setting this bit causes even parity to be transmitted and expected.
+ * Otherwise, odd parity is used.
+ * Bit 3: Parity Enable (PEN). When set to "1", a parity bit is inserted
+ * between the last bit of the data and the Stop Bit. The UART will also
+ * expect parity to be present in the received data.
+ * Bit 2: Number of Stop Bits (STB). If set to "1" and using 5-bit data words,
+ * 1.5 Stop Bits are transmitted and expected in each data word. For
+ * 6, 7 and 8-bit data words, 2 Stop Bits are transmitted and expected.
+ * When this bit is set to "0", one Stop Bit is used on each data word.
+ * Bit 1: Word Length Select Bit #1 (WLSB1)
+ * Bit 0: Word Length Select Bit #0 (WLSB0)
+ * Together these bits specify the number of bits in each data word.
+ * 1 0 Word Length
+ * 0 0 5 Data Bits
+ * 0 1 6 Data Bits
+ * 1 0 7 Data Bits
+ * 1 1 8 Data Bits
+ *
+ * SniffUSB observations: Bit 7 seems not to be used. There seem to be two bugs
+ * in the Win98 driver: the break does not work (bit 6 is not asserted) and the
+ * stick parity bit is not cleared when set once. The LCR can also be read
+ * back with USB request 6 but this has never been observed with SniffUSB.
+ *
+ *
+ * Modem Control Register (MCR)
+ * ----------------------------
+ *
+ * BmRequestType: 0x40 (0100 0000B)
+ * bRequest: 0x0a
+ * wValue: 0x0000
+ * wIndex: 0x0000
+ * wLength: 0x0001
+ * Data: MCR (Bit 4..7, see below)
+ *
+ * Bit 7: Reserved, always 0.
+ * Bit 6: Reserved, always 0.
+ * Bit 5: Reserved, always 0.
+ * Bit 4: Loop-Back Enable. When set to "1", the UART transmitter and receiver
+ * are internally connected together to allow diagnostic operations. In
+ * addition, the UART modem control outputs are connected to the UART
+ * modem control inputs. CTS is connected to RTS, DTR is connected to
+ * DSR, OUT1 is connected to RI, and OUT 2 is connected to DCD.
+ * Bit 3: OUT 2. An auxiliary output that the host processor may set high or
+ * low. In the IBM PC serial adapter (and most clones), OUT 2 is used
+ * to tri-state (disable) the interrupt signal from the
+ * 8250/16450/16550 UART.
+ * Bit 2: OUT 1. An auxiliary output that the host processor may set high or
+ * low. This output is not used on the IBM PC serial adapter.
+ * Bit 1: Request to Send (RTS). When set to "1", the output of the UART -RTS
+ * line is Low (Active).
+ * Bit 0: Data Terminal Ready (DTR). When set to "1", the output of the UART
+ * -DTR line is Low (Active).
+ *
+ * SniffUSB observations: Bit 2 and 4 seem not to be used but bit 3 has been
+ * seen _always_ set.
+ *
+ *
+ * Modem Status Register (MSR)
+ * ---------------------------
+ *
+ * BmRequestType: 0xc0 (1100 0000B)
+ * bRequest: 0x02
+ * wValue: 0x0000
+ * wIndex: 0x0000
+ * wLength: 0x0001
+ * Data: MSR (see below)
+ *
+ * Bit 7: Data Carrier Detect (CD). Reflects the state of the DCD line on the
+ * UART.
+ * Bit 6: Ring Indicator (RI). Reflects the state of the RI line on the UART.
+ * Bit 5: Data Set Ready (DSR). Reflects the state of the DSR line on the UART.
+ * Bit 4: Clear To Send (CTS). Reflects the state of the CTS line on the UART.
+ * Bit 3: Delta Data Carrier Detect (DDCD). Set to "1" if the -DCD line has
+ * changed state one more more times since the last time the MSR was
+ * read by the host.
+ * Bit 2: Trailing Edge Ring Indicator (TERI). Set to "1" if the -RI line has
+ * had a low to high transition since the last time the MSR was read by
+ * the host.
+ * Bit 1: Delta Data Set Ready (DDSR). Set to "1" if the -DSR line has changed
+ * state one more more times since the last time the MSR was read by the
+ * host.
+ * Bit 0: Delta Clear To Send (DCTS). Set to "1" if the -CTS line has changed
+ * state one more times since the last time the MSR was read by the
+ * host.
+ *
+ * SniffUSB observations: the MSR is also returned as first byte on the
+ * interrupt-in endpoint 0x83 to signal changes of modem status lines. The USB
+ * request to read MSR cannot be applied during normal device operation.
+ *
+ *
+ * Line Status Register (LSR)
+ * --------------------------
+ *
+ * Bit 7 Error in Receiver FIFO. On the 8250/16450 UART, this bit is zero.
+ * This bit is set to "1" when any of the bytes in the FIFO have one
+ * or more of the following error conditions: PE, FE, or BI.
+ * Bit 6 Transmitter Empty (TEMT). When set to "1", there are no words
+ * remaining in the transmit FIFO or the transmit shift register. The
+ * transmitter is completely idle.
+ * Bit 5 Transmitter Holding Register Empty (THRE). When set to "1", the
+ * FIFO (or holding register) now has room for at least one additional
+ * word to transmit. The transmitter may still be transmitting when
+ * this bit is set to "1".
+ * Bit 4 Break Interrupt (BI). The receiver has detected a Break signal.
+ * Bit 3 Framing Error (FE). A Start Bit was detected but the Stop Bit did
+ * not appear at the expected time. The received word is probably
+ * garbled.
+ * Bit 2 Parity Error (PE). The parity bit was incorrect for the word
+ * received.
+ * Bit 1 Overrun Error (OE). A new word was received and there was no room
+ * in the receive buffer. The newly-arrived word in the shift register
+ * is discarded. On 8250/16450 UARTs, the word in the holding register
+ * is discarded and the newly- arrived word is put in the holding
+ * register.
+ * Bit 0 Data Ready (DR). One or more words are in the receive FIFO that the
+ * host may read. A word must be completely received and moved from
+ * the shift register into the FIFO (or holding register for
+ * 8250/16450 designs) before this bit is set.
+ *
+ * SniffUSB observations: the LSR is returned as second byte on the
+ * interrupt-in endpoint 0x83 to signal error conditions. Such errors have
+ * been seen with minicom/zmodem transfers (CRC errors).
+ *
+ *
+ * Unknown #1
+ * -------------------
+ *
+ * BmRequestType: 0x40 (0100 0000B)
+ * bRequest: 0x0b
+ * wValue: 0x0000
+ * wIndex: 0x0000
+ * wLength: 0x0001
+ * Data: 0x00
+ *
+ * SniffUSB observations (Nov 2003): With the MCT-supplied Windows98 driver
+ * (U2SPORT.VXD, "File version: 1.21P.0104 for Win98/Me"), this request
+ * occurs immediately after a "Baud rate (divisor)" message. It was not
+ * observed at any other time. It is unclear what purpose this message
+ * serves.
+ *
+ *
+ * Unknown #2
+ * -------------------
+ *
+ * BmRequestType: 0x40 (0100 0000B)
+ * bRequest: 0x0c
+ * wValue: 0x0000
+ * wIndex: 0x0000
+ * wLength: 0x0001
+ * Data: 0x00
+ *
+ * SniffUSB observations (Nov 2003): With the MCT-supplied Windows98 driver
+ * (U2SPORT.VXD, "File version: 1.21P.0104 for Win98/Me"), this request
+ * occurs immediately after the 'Unknown #1' message (see above). It was
+ * not observed at any other time. It is unclear what other purpose (if
+ * any) this message might serve, but without it, the USB/RS-232 adapter
+ * will not write to RS-232 devices which do not assert the 'CTS' signal.
+ *
+ *
+ * Flow control
+ * ------------
+ *
+ * SniffUSB observations: no flow control specific requests have been realized
+ * apart from DTR/RTS settings. Both signals are dropped for no flow control
+ * but asserted for hardware or software flow control.
+ *
+ *
+ * Endpoint usage
+ * --------------
+ *
+ * SniffUSB observations: the bulk-out endpoint 0x1 and interrupt-in endpoint
+ * 0x81 is used to transmit and receive characters. The second interrupt-in
+ * endpoint 0x83 signals exceptional conditions like modem line changes and
+ * errors. The first byte returned is the MSR and the second byte the LSR.
+ *
+ *
+ * Other observations
+ * ------------------
+ *
+ * Queued bulk transfers like used in visor.c did not work.

+ *
+ * This info was gleaned from opening a Belkin F5U109 DB9 USB serial
+ * adaptor, which turns out to simply be a re-badged U232-P9. We
+ * know this because there is a sticky label on the circuit board
+ * which says "U232-P9" ;-)
+ *
+ * The circuit board inside the adaptor contains a Philips PDIUSBD12
+ * USB endpoint chip and a Philips P87C52UBAA microcontroller with
+ * embedded UART. Exhaustive documentation for these is available at:
+ *
+ * http://www.semiconductors.philips.com/pip/p87c52ubaa
+ * http://www.nxp.com/acrobat_download/various/PDIUSBD12_PROGRAMMING_GUIDE.pdf
+ *
+ * Thanks to Julian Highfield for the pointer to the Philips database.

+
+ This driver exists because the "normal" serial driver doesn't work too well
+ with GSM modems. Issues:
+ - data loss -- one single Receive URB is not nearly enough
+ - nonstandard flow (Option devices) control
+ - controlling the baud rate doesn't make sense
+
+ This driver is named "option" because the most common device it's
+ used for is a PC-Card (with an internal OHCI-USB interface, behind
+ which the GSM interface sits), made by Option Inc.
+
+ Some of the "one port" devices actually exhibit multiple USB instances
+ on the USB bus. This is not a bug, these ports are used for different
+ device features.

+ * Warning! You use this driver on your own risk! The only official
+ * description of this device I have is datasheet from manufacturer,
+ * and it doesn't contain almost any information needed to write a driver.
+ * Almost all knowlegde used while writing this driver was gathered by:
+ * - analyzing traffic between device and the M$ Windows 2000 driver,
+ * - trying different bit combinations and checking pin states
+ * with a voltmeter,
+ * - receiving malformed frames and producing buffer overflows
+ * to learn how errors are reported,
+ * So, THIS CODE CAN DESTROY OTi-6858 AND ANY OTHER DEVICES, THAT ARE
+ * CONNECTED TO IT!
+ *
+ * See Documentation/usb/usb-serial.txt for more information on using this
+ * driver
+ *
+ * TODO:
+ * - implement correct flushing for ioctls and oti6858_close()
+ * - check how errors (rx overflow, parity error, framing error) are reported
+ * - implement oti6858_break_ctl()
+ * - implement more ioctls
+ * - test/implement flow control
+ * - allow setting custom baud rates

+ * The encapsultaion is designed to overcome difficulties with some USB
+ * hardware.
+ *
+ * While the USB protocol has a CRC over the data while in transit, i.e. while
+ * being carried over the bus, there is no end to end protection. If the
+ * hardware has any problems getting the data into or out of the USB transmit
+ * and receive FIFO's then data can be lost.
+ *
+ * This protocol adds a two byte trailer to each USB packet to specify the
+ * number of bytes of valid data and a 10 bit CRC that will allow the receiver
+ * to verify that the entire USB packet was received without error.
+ *
+ * Because in this case the sender and receiver are the class and function
+ * drivers there is now end to end protection.
+ *
+ * There is an additional option that can be used to force all transmitted
+ * packets to be padded to the maximum packet size. This provides a work
+ * around for some devices which have problems with small USB packets.
+ *
+ * Assuming a packetsize of N:
+ *
+ * 0..N-2 data and optional padding
+ *
+ * N-2 bits 7-2 - number of bytes of valid data
+ * bits 1-0 top two bits of 10 bit CRC
+ * N-1 bottom 8 bits of 10 bit CRC
+ *
+ *
+ * | Data Length | 10 bit CRC |
+ * + 7 . 6 . 5 . 4 . 3 . 2 . 1 . 0 | 7 . 6 . 5 . 4 . 3 . 2 . 1 . 0 +
+ *
+ * The 10 bit CRC is computed across the sent data, followed by the trailer
+ * with the length set and the CRC set to zero. The CRC is then OR'd into
+ * the trailer.
+ *
+ * When received a 10 bit CRC is computed over the entire frame including
+ * the trailer and should be equal to zero.
+ *
+ * Two module parameters are used to control the encapsulation, if both are
+ * turned of the module works as a simple serial device with NO
+ * encapsulation.
+ *
+ * See linux/drivers/usbd/serial_fd for a device function driver
+ * implementation of this.
