Please clarify this. Does the Everex fail in the same way as the MicroCom,
or all the time? Also, could you briefly discuss the "AT dumb mode"? My hayes
modem hacking is limited to getting the damn thing running with my terminal
emulator...

How do you 'understand' that the Hayes modems work? Have you used them, or
heard reports? If the latter, can you tell us who it is that has the Hayes
modems running?

If this is true then you are ahead of the game. On some other System V
systems, you have to kill the modem BY HAND to get it to work again. There
has been much talk about this in various newsgroups (notably pubnet.something)
but no definitive conclusion was reached, other than that Hayes-type modems
were risky business for SysV machines.

There are other problems. In some cases, if you call in on a 2400 bps modem
at 1200, it won't reset the speed. This can cause major problems if your
news feed is trying to call at 2400.

Note that all this is not rumor. I use a system daily that suffers from the
problems I mentioned. It is NOT an A/UX machine, however. If I knew for a
fact that A/UX were susceptible or immune wrt these problems, I wouldn't be
posting...

Does anyone have a non-Hayes-compatible, non-Telebit modem working under A/UX
for DIAL-IN use?

Sigh...
