[comp.sys.sgi] modem problem

"0000-Admin@UCBVAX.BERKELEY.EDU (06/09/91)

For a long time (since before I became associated with uzi.mit.edu), there
has been a modem connection on ttym2.  Recently, it has stopped functioning.
The following message has appeared in the SYSLOG:

grcond[1042]: CIO: getty: ioctl(TCGETA2, "ttym2"): errno=6

On the modem, all of the status lights remain on full time.  The trouble is,
I'm away from my machine for the next several weeks, limiting how much I
can fool around in person.  So my question is pretty basic: does this sound
like a software thing that I can repair from afar, or is it a hardware thing
with the modem that I'll have to wait till I get back to MIT to fix?
A second, identical modem was evidently substituted for the one that was
previously connected, and it evidently also failed to work.  On the other
hand, nothing changed on the IRIS end as far as I can tell.  Also, the 
cable connection seems to be fine, I'm told.
I've read the manual stuff on the error and ioctl(), etc., just to check
up and see if there was something that I was missing.  Error 6 seems to just
indicate that there is a communication problem -- either the IRIS is trying
to access a feature of the modem that isn't there or the modem is, in
effect, "off line".  I guess I wish I knew more about how it was originally
configured.  If anyone has any potentially useful experiences with
connecting modems to PIs, please send along some e-mail.
Thanks,
