I am working on a C program to print a file on the printer attached to
my vt100 terminal.  Actually it is an IBM-PC running Kermit.  I know
what codes to send to turn the printer on and off.  I open the "dev/tty"
file to fool any program which uses my program into passing the
characters through (i.e I do not merely send them to stdout or stderr).

Now I want to force the characters to be sent with 8 bits, no parity.
The parity bit causes my Epson to print in italics, and really confuses
an HP LaserJet.  I cannot configure my terminal for even parity for
other reasons.  I studied the man pages for a long time, trying to
figure out what system call would set the outgoing characters to no
parity, without success.  If anyone can help me, I would appreciate it.

I am using a Sun 3/260 running SunOS 4.0.1.  -David-
