modem keeps disappearing

[Claude Jones]

I'm having a disappearing modem problem. I put in the computer, it gets 
recognized by kudzu, and it comes up working. I use it to dial in to an 
old mainframe. Kermit sees it, and I have ProComm for DOS running under 
dosemu. All seems well. I shut down the computer, and when it comes back 
up, it has disappeared. So far, I've only been able to recover it by 
removing it and rebooting, and then reinstalling it and rebooting. It 
seemed to be a problem with a lockfile earlier on, but, that's no longer 
the case. Can anyone offer an idea? I've searched the list and read the 
configuration manuals from Redhat, but there is precious little said 
about modems for old-style dialup.
