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. >We had a locally hacked version of the Tahoe lpd, but only for printing >remotely. It looks like IRIX 4.0 has a Berkeley version.

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. - Scott -- Scott Presnell +1 (415) 476-9890 Pharm.

We use the SGI supplied lpr/lpd and haven't had any problems with it. We have printers connected to parallel ports on two SGI machines. We also have printers on some Sun's and we can send files to any of the printers from any of the machines. Brent L.
