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.

LT		 1142 * - set tty->termios->c_cflag speed to B38400
1143 * - set your real speed in tty->alt_speed; it gets ignored when
1144 * alt_speed==0, (or)
464cbb24
AC		 1145 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1146 * follows:
1147 * flags & ASYNC_SPD_MASK == ASYNC_SPD_[HI, VHI, SHI, WARP],
1148 * this just sets alt_speed to (HI: 57600, VHI: 115200,
1149 * SHI: 230400, WARP: 460800)
1da177e4
LT		 1150 * ** Steps 1, 2 are done courtesy of tty_get_baud_rate
1151 * 3. You can also set baud rate by setting custom divisor as follows
1152 * - set tty->termios->c_cflag speed to B38400
464cbb24
AC		 1153 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1154 * follows:
1da177e4
LT		 1155 * o flags & ASYNC_SPD_MASK == ASYNC_SPD_CUST
1156 * o custom_divisor set to baud_base / your_new_baudrate
464cbb24
AC		 1157 * ** Step 3 is done courtesy of code borrowed from serial.c
