Two Mac IIcx systems on my network seem to have lost the capability to use their modem ports. They were both attached to the same data switch (via the modem port), so I'm guessing something bad came down the line to cause this (I have other Macs on the data switch, but they were turned off when the problem came up. They are still working fine). Does anyone know how I can find exactly what is wrong and how I might be able to fix it? I really don't want to call in a service person unless I have to. Thanks in advance. George -- / George D.

There have been a couple of postings lately from people whose serial
ports have have been disabled. That happened to me a while ago (effect
of a MIDI device), and a solution was kindly provided by Matthew
Kaufman (matthew@ucscb.ucsc.edu). He also posted it, so I imagine he
has no objection to its being posted again. It's short, and it worked
fine for me. It just resets the PRAM, which certain devices can put
into a pathological state that is otherwise hard to recover from.

After getting the motherboard replaced on my SE, I found out it was all a software problem. ;-(. Zapping the PRAM had no effect - the ports consistantly gave an error 95 (or was it 94?). I'd been using Farallon's "Traffic Watch" software on our net, and it leaves the ports dirty when you quit. After following up with Farallon, they gave me a program called "ResetPorts", and that did the trick. They also updated the version of Traffic Watch I was using, and that seemed to help the port problem. Now the ports aren't working again, and ResetPorts doesn't help. I don't know _what_ the cause is this time - but I'm upgrading to an SE30, so it'll soon be Apple's problem. ;^) In summary, I'd exhaust all software solutions before you take the *expensive* plunge of hardware repair (replacement).
