133 * The 8U232AM has the same API as the sio except for:

136 * o 230400 at 12MHz

Alan Cox464cbb22008-07-22 11:11:23 +01001118 * The logic involved in setting the baudrate can be cleanly split into
1119 * 3 steps.
Linus Torvalds1da177e2005-04-16 15:20:36 -07001120 * 1. Standard baud rates are set in tty->termios->c_cflag
Alan Cox464cbb22008-07-22 11:11:23 +01001121 * 2. If these are not enough, you can set any speed using alt_speed as
1122 * follows:
Linus Torvalds1da177e2005-04-16 15:20:36 -07001123 * - set tty->termios->c_cflag speed to B38400
1124 * - set your real speed in tty->alt_speed; it gets ignored when
1125 * alt_speed==0, (or)
Alan Cox464cbb22008-07-22 11:11:23 +01001126 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1127 * follows:
1128 * flags & ASYNC_SPD_MASK == ASYNC_SPD_[HI, VHI, SHI, WARP],
1129 * this just sets alt_speed to (HI: 57600, VHI: 115200,
1130 * SHI: 230400, WARP: 460800)
Linus Torvalds1da177e2005-04-16 15:20:36 -07001131 * ** Steps 1, 2 are done courtesy of tty_get_baud_rate
1132 * 3. You can also set baud rate by setting custom divisor as follows
1133 * - set tty->termios->c_cflag speed to B38400
Alan Cox464cbb22008-07-22 11:11:23 +01001134 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1135 * follows:
Linus Torvalds1da177e2005-04-16 15:20:36 -07001136 * o flags & ASYNC_SPD_MASK == ASYNC_SPD_CUST
1137 * o custom_divisor set to baud_base / your_new_baudrate
Alan Cox464cbb22008-07-22 11:11:23 +01001138 * ** Step 3 is done courtesy of code borrowed from serial.c
1139 * I should really spend some time and separate + move this common
1140 * code to serial.c, it is replicated in nearly every serial driver
1141 * you see.
