121 * The 8U232AM has the same API as the sio except for:
122 * - it can support MUCH higher baudrates; up to:
123 * o 921600 for RS232 and 2000000 for RS422/485 at 48MHz
124 * o 230400 at 12MHz
125 * so .. 8U232AM's baudrate setting codes are different
126 * - it has a two byte status code.
127 * - it returns characters every 16ms (the FTDI does it every 40ms)
128 *
129 * the bcdDevice value is used to differentiate FT232BM and FT245BM from
130 * the earlier FT8U232AM and FT8U232BM. For now, include all known VID/PID
131 * combinations in both tables.

1170 * - set your real speed in tty->alt_speed; it gets ignored when

464cbb24

1174 * flags & ASYNC_SPD_MASK == ASYNC_SPD_[HI, VHI, SHI, WARP],
1175 * this just sets alt_speed to (HI: 57600, VHI: 115200,
1176 * SHI: 230400, WARP: 460800)
1da177e4
LT		 1177 * ** Steps 1, 2 are done courtesy of tty_get_baud_rate

1179 * - set tty->termios->c_cflag speed to B38400
464cbb24
AC		 1180 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1181 * follows:
1da177e4
LT		 1182 * o flags & ASYNC_SPD_MASK == ASYNC_SPD_CUST
1183 * o custom_divisor set to baud_base / your_new_baudrate
