The problem in using Supra v32bis modems is due to uutry needing to 
see carrier detect on the modem before it will communicate. While running a 
uugetty is one way, possibly an easier way is to load the "Macintosh" profile
into the Supra as the default power-on profile. Most Supra modems shipped 
individually or as part of a DOS/WINDOWS package, use factory stored profile
number 2 as the power-up profile, which is listed in the Supra manual as
being for IBM (and all others except Macintosh), and asserts an AT&C1, 
which tells the modem to have DCD reflect a remote carrier. What the SGI
needs is to see DCD high before uutry will talk to the modem. This implies
an AT&C (or AT&C0) option, which is part of the Macintosh profile. If your
modem was not shipped specifically for use with a Macintosh, it will have 
the wrong profile (as far as using on an SGI goes) loaded as the power-up
profile. Here's how you change that....

start a session with the modem via cu

issue an AT&F1<enter>   /* Load Macintosh profile as active profile */
issue an AT&W0<enter>   /* Save this as user-stored profile 0 (or use 
                           an AT&W1 if you wish to store it as profile 1) */
issue an AT&Y0<enter>   /* To set stored user profile 0 as the power-up 
                           profile (or use AT&Y1 if you issued an AT&W1 ) */

This should do the trick... I brought my Supra in to the office and we tried
it on my indigo... uutry worked flawlessly, but if we broke out of the loop,
we had to remember to kill the uucico process before we tried it again.

I have sent e-mail to Supra suggesting that they may want to modify
their manual in future revisions to suggest &F1 as the profile for 
Macs as well as UUCP use.
Cheers,
Kevin
