Thank you tye, ptkdb, and sgifford for your excellent replies.

The pseudo-tty code sgifford posted worked wonderfully in Linux, but not when I moved to my final target, SunOS. I eventually found a small C program called ircflush, part of the ircII distribution that does the same thing and seems to work in SunOS. I also looked into using IPC::Run but it does not connect file handles to pseudo-ttys.
