[comp.sys.next] Modems

greid@adobe.com (Glenn Reid) (08/16/89)

I have a NeXT cube running UUCP.  Everything works okay,
but the two computers with which I have connections seem
to have a very high failure rate logging in.  It isn't
broken, because the connection is always made eventually,
but it seems to hang an awful lot.  To be more precise,
their system calls mine, the modem answers and the connection
is established, but there is basically no response from
the "getty" process on my system, the receive and transmit
lights on the modem do nothing, and after about 30 seconds
the calling system hangs up with a FAILED (LOGIN) message
in the log file.

Similarly, trying to log in through tip(1) from the remote
machine often is greeted with null behavior.  I am now
attributing this to a weird modem.  I bought a brand new
(and brand X) Avatex 2400 baud Hayes-compatible modem.  I
haven't had any problems with it when I dial out, but maybe
its auto-answer behavior is not up to spec, especially when
the calling modem has to go through some baud rate
negotiations or something.

Has anyone had any similar experiences, or have any
suggestions?  Should I spend three times what I paid for this
modem and get a real Hayes modem?  Should I spend ten
times it and get a Trailblazer :-?  Is the problem my
modem or "getty" on the NeXT?

Thanks for any insights,

[modem problems, especially autoanswer]

Yes.  I have had similar problems.

If I have the same modem do autoanswer and dial out, I have a real problem.
If I have port A to my Migent modem
And I have port B to my US Robotics
I can set up my Migent to dial out but not autoanswer
and I can set up the robotics to autoanswer but not dial out.

I can switch the ports, but the modems act the same.

Hooking up a modem is pretty easy.  (See article in BuzzNUG Buzzings #1).
Use a Mac Modem cable, grab a copy of Kermit if you can or if you can't,
use "tip".  Edit your /etc/remote file (copy a9600 two lines to another
location and change the 9600's in those 2 lines to 2400 or 1200 or 4800).
Do a tip a1200, a2400, (you get the idea) and then use "AT" commands as
normal.  If you can't figure out what to do (from these vague instructions),
either contact me at erica@kong.gatech.edu or grab a copy of the Buzzings
from a friend.
