116 * The 8U232AM has the same API as the sio except for:
117 * - it can support MUCH higher baudrates; up to:
118 * o 921600 for RS232 and 2000000 for RS422/485 at 48MHz
119 * o 230400 at 12MHz
120 * so .. 8U232AM's baudrate setting codes are different
121 * - it has a two byte status code.
122 * - it returns characters every 16ms (the FTDI does it every 40ms)
