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

1002 * this just sets alt_speed to (HI: 57600, VHI: 115200,

1da177e4

464cbb24
AC		 1007 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as

1010 * o custom_divisor set to baud_base / your_new_baudrate
