138 * The 8U232AM has the same API as the sio except for:
139 * - it can support MUCH higher baudrates; up to:
140 * o 921600 for RS232 and 2000000 for RS422/485 at 48MHz
141 * o 230400 at 12MHz
142 * so .. 8U232AM's baudrate setting codes are different
143 * - it has a two byte status code.
144 * - it returns characters every 16ms (the FTDI does it every 40ms)
145 *
146 * the bcdDevice value is used to differentiate FT232BM and FT245BM from
147 * the earlier FT8U232AM and FT8U232BM. For now, include all known VID/PID
148 * combinations in both tables.
