We've recently installed ULTRIX 4.1 on a VAX 8800. Modem lines that previously worked fine as "shared" lines (both incoming and outgoing transactions allowed) now work reliably only for incoming transactions. More often than not for outgoing calls, 'tip' returns "all ports busy", and uucp finds requested devices "ALREADY IN USE", when inspection of the modems in question shows this status to be false. All seven modem lines come off our DMB32. DEC Software Support has no immediate ideas on what could be happening. Has anyone else run into this and fixed it? Any and all ideas will be gratefully accepted. Email or post as you see fit. Thanks in advance. Agfa Compugraphic Corp Dick Lucas Wilmington, MA lucas@cg-atla.agfa.com

Worked fine before under what? 4.0? Or 3.something? Check the permissions and the group mode on tip and the uucp programs. (You can use setld to verify the subset they are in -- for example setld -v UDTCOMM410 -- to see if the modes, etc. are correct.) Sounds like tip and/or uucp are not running with setgid mode turned on and/or are not in a group allowing them to open the tty. (Need to be in group tty. What does a ls -lg on your executables and on the relevant /dev/tty* files show?)
