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

1108 * - set your real speed in tty->alt_speed; it gets ignored when

1115 * ** Steps 1, 2 are done courtesy of tty_get_baud_rate
