137 * The 8U232AM has the same API as the sio except for:
138 * - it can support MUCH higher baudrates; up to:
139 * o 921600 for RS232 and 2000000 for RS422/485 at 48MHz
140 * o 230400 at 12MHz
141 * so .. 8U232AM's baudrate setting codes are different
142 * - it has a two byte status code.
143 * - it returns characters every 16ms (the FTDI does it every 40ms)

1079 * 3 steps.
Linus Torvalds1da177e2005-04-16 15:20:36 -0700[diff] [blame]1080 * 1. Standard baud rates are set in tty->termios->c_cflag
Alan Cox464cbb22008-07-22 11:11:23 +0100[diff] [blame]1081 * 2. If these are not enough, you can set any speed using alt_speed as
1082 * follows:
Linus Torvalds1da177e2005-04-16 15:20:36 -0700[diff] [blame]1083 * - set tty->termios->c_cflag speed to B38400
1084 * - set your real speed in tty->alt_speed; it gets ignored when
1085 * alt_speed==0, (or)
Alan Cox464cbb22008-07-22 11:11:23 +0100[diff] [blame]1086 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1087 * follows:
1088 * flags & ASYNC_SPD_MASK == ASYNC_SPD_[HI, VHI, SHI, WARP],
1089 * this just sets alt_speed to (HI: 57600, VHI: 115200,
1090 * SHI: 230400, WARP: 460800)
Linus Torvalds1da177e2005-04-16 15:20:36 -0700[diff] [blame]1091 * ** Steps 1, 2 are done courtesy of tty_get_baud_rate
1092 * 3. You can also set baud rate by setting custom divisor as follows
1093 * - set tty->termios->c_cflag speed to B38400
Alan Cox464cbb22008-07-22 11:11:23 +0100[diff] [blame]1094 * - call TIOCSSERIAL ioctl with (struct serial_struct) set as
1095 * follows:
Linus Torvalds1da177e2005-04-16 15:20:36 -0700[diff] [blame]1096 * o flags & ASYNC_SPD_MASK == ASYNC_SPD_CUST

Alan Cox464cbb22008-07-22 11:11:23 +0100[diff] [blame]1098 * ** Step 3 is done courtesy of code borrowed from serial.c
1099 * I should really spend some time and separate + move this common
1100 * code to serial.c, it is replicated in nearly every serial driver
