You should look at the manual pages for stty(1), ioctl(2), and termio(4).
Termio(4) will explain all about how to use the ioctl() function to set
baud rate, parity, and a bunch of other parameters on tty ports.  The stty
command can be used to make these same settings from a shell prompt or
within a shell script (or even with a C program using system(3), if you
are so inclined, but ioctl is the preferred method).

If you want to set the tty settings from within the lpr spooler, use the
`ms' capability in the printcap.  You pass it a set of arguments to be
used with stty(1), e.g.:

	:ms=parenb -parodd cs7 -cstopb:
