138 * The 8U232AM has the same API as the sio except for:
139 * - it can support MUCH higher baudrates; up to:

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)
