I tried and failed when I was doing the HDB port. There are 2 problems: 1) You have to create a lock file so that uugetty knows it's been locked out of using the line. 2) Only one process can have a ph port open at a time - things get really confused and the second process just hangs forever on a read. -- Jonathan Clark jhc@mtune.att.com, attmail!jonathan The Englishman never enjoys himself except for some noble purpose.

I don't know. It's a bug in the ph driver, I think, but I once spent two days looking for it and failed even to make a dent in the problem. It's pretty messy in there, and the interaction between the ph driver and the tty driver doesn't help. I seem to remember once hearing a story that a fix for this had been found and was on a FIXDISK, but that was probably just a rumour. -- Jonathan Clark jhc@mtune.att.com, attmail!jonathan The Englishman never enjoys himself except for some noble purpose.
