* The 8U232AM has the same API as the sio except for:
|
|
* - it can support MUCH higher baudrates; up to:
|
|
* o 921600 for RS232 and 2000000 for RS422/485 at 48MHz
|
|
* o 230400 at 12MHz
|
|
* so .. 8U232AM's baudrate setting codes are different
|
|
* - it has a two byte status code.
|
|
* - it returns characters every 16ms (the FTDI does it every 40ms)
|
|
*
|
|
* the bcdDevice value is used to differentiate FT232BM and FT245BM from
|
|
* the earlier FT8U232AM and FT8U232BM. For now, include all known VID/PID
|
|
* combinations in both tables.
|
|
* FIXME: perhaps bcdDevice can also identify 12MHz FT8U232AM devices,
|
|
* but I don't know if those ever went into mass production. [Ian Abbott]

* The logic involved in setting the baudrate can be cleanly split into
|
|
* 3 steps.
|
|
* 1. Standard baud rates are set in tty->termios->c_cflag
|
|
* 2. If these are not enough, you can set any speed using alt_speed as
|
|
* follows:
|
|
* - set tty->termios->c_cflag speed to B38400
|
|
* - set your real speed in tty->alt_speed; it gets ignored when
|
|
* alt_speed==0, (or)
|
|
* - call TIOCSSERIAL ioctl with (struct serial_struct) set as
|
|
* follows:
|
|
* flags & ASYNC_SPD_MASK == ASYNC_SPD_[HI, VHI, SHI, WARP],
|
|
* this just sets alt_speed to (HI: 57600, VHI: 115200,
|
|
* SHI: 230400, WARP: 460800)
|
|
* ** Steps 1, 2 are done courtesy of tty_get_baud_rate
|
|
* 3. You can also set baud rate by setting custom divisor as follows
|
|
* - set tty->termios->c_cflag speed to B38400
|
|
* - call TIOCSSERIAL ioctl with (struct serial_struct) set as
|
|
* follows:
|
|
* o flags & ASYNC_SPD_MASK == ASYNC_SPD_CUST
|
|
* o custom_divisor set to baud_base / your_new_baudrate
|
|
* ** Step 3 is done courtesy of code borrowed from serial.c
|
|
* I should really spend some time and separate + move this common
|
|
* code to serial.c, it is replicated in nearly every serial driver
|
|
* you see.
