/*
 * 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.
150 151
 * FIXME: perhaps bcdDevice can also identify 12MHz FT8U232AM devices,
 * but I don't know if those ever went into mass production. [Ian Abbott]
