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

1127 * follows:
1128 * flags & ASYNC_SPD_MASK == ASYNC_SPD_[HI, VHI, SHI, WARP],
1129 * this just sets alt_speed to (HI: 57600, VHI: 115200,
