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