Many properties of the serial driver can be controlled by the 'termios' interface (man termios). You can get some idea about what the ioctls do by looking at the source code of the driver (/usr/src/linux/drivers/char/serial.c). If you have access to a Sun you can also consult its 'man 4 termio' page where Sun's ioctls are described (Sun's are not all the same as linux' though).
