121 * The 8U232AM has the same API as the sio except for:
122 * - it can support MUCH higher baudrates; up to:
123 * o 921600 for RS232 and 2000000 for RS422/485 at 48MHz
124 * o 230400 at 12MHz
125 * so .. 8U232AM's baudrate setting codes are different
126 * - it has a two byte status code.
127 * - it returns characters every 16ms (the FTDI does it every 40ms)
128 *
129 * the bcdDevice value is used to differentiate FT232BM and FT245BM from
130 * the earlier FT8U232AM and FT8U232BM. For now, include all known VID/PID

1256 * 2. If these are not enough, you can set any speed using alt_speed as
1257 * follows:
1258 * - set tty->termios->c_cflag speed to B38400
1259 * - set your real speed in tty->alt_speed; it gets ignored when
1260 * alt_speed==0, (or)
1261 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1262 * follows:
1263 * flags & ASYNC_SPD_MASK == ASYNC_SPD_[HI, VHI, SHI, WARP],
1264 * this just sets alt_speed to (HI: 57600, VHI: 115200,
1265 * SHI: 230400, WARP: 460800)
1266 * ** Steps 1, 2 are done courtesy of tty_get_baud_rate
1267 * 3. You can also set baud rate by setting custom divisor as follows
1268 * - set tty->termios->c_cflag speed to B38400
1269 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1270 * follows:
1271 * o flags & ASYNC_SPD_MASK == ASYNC_SPD_CUST
1272 * o custom_divisor set to baud_base / your_new_baudrate
1273 * ** Step 3 is done courtesy of code borrowed from serial.c
1274 * I should really spend some time and separate + move this common
1275 * code to serial.c, it is replicated in nearly every serial driver
1276 * you see.
