Modem Problems under ULTRIX 4.1

[Dick Lucas]

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.
