There was one substantial set of changes that I made to the transcript 2.1
software - the BSD version of pscomm expects to use the BSD signal
semantics where a system call interrupted by a signal will be restarted.
This is currently not available under IRIX, so I blocked signals around
these critical regions.  That stopped the core dumps from pscomm.

IRIX 3.3 seems to have /usr/etc/lpd (it's on the dist tapes) - but I
haven't tried it for directly connected printers.

I also have patches to lpd to use termio stuff (I think I got them from BU
:-).  But, we run a modified version of lpd that handles printing via
terminal servers - one of our iri operates in this manner.  This particular
setup is sort of between printing to a directly connected port and sending
to another machine - it was different enough to expose problems in SIGCHLD
handling, wait() timing, and a few random BSDisms in lpd, and the pscomm
problems.  If anyone can use these changes, let me know.
