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
131 * combinations in both tables.
