127 * The 8U232AM has the same API as the sio except for:
128 * - it can support MUCH higher baudrates; up to:
129 * o 921600 for RS232 and 2000000 for RS422/485 at 48MHz
130 * o 230400 at 12MHz
131 * so .. 8U232AM's baudrate setting codes are different
132 * - it has a two byte status code.
133 * - it returns characters every 16ms (the FTDI does it every 40ms)
134 *
135 * the bcdDevice value is used to differentiate FT232BM and FT245BM from
136 * the earlier FT8U232AM and FT8U232BM. For now, include all known VID/PID
137 * combinations in both tables.
8f977e42
IA		 138 * FIXME: perhaps bcdDevice can also identify 12MHz FT8U232AM devices,
139 * but I don't know if those ever went into mass production. [Ian Abbott]
