I'm having trouble using a Supra FAX modem with my NeXTstation Color
(not turbo). Most things work, but other modems are having problems
getting in. Anybody out there recognize these symtpoms or have any
experience with this?

I have a Supra FAX/Modem V.32bis which I have successfully used to dial
out to the world (both logging on via kermit and having uucico conect and
do its thing). I am running it at 38400 with hardware flow control.

Unfortunately, when another modem tries to connect to it things kind of
go out the window. In one case, a modem that definitely can connect
to other modems can't evn get past the squawking noises to establish a
carrier. I can't remember the type of this modem, but it's either a
US Robotics or a Telebit - something capable of high speed.

I have /etc/ttys set up as such:

ttydfa  "/usr/etc/getty std.9600"   dialup      on
#ttydfa  "/usr/etc/getty std.38400"   dialup      on
#ttydfa etc. for each baud rate ... all commented out except one

And /etc/gettytab has:

2|std.9600|9600-baud:\
    :sp#9600:
g|std.38400|38400-baud:\
    :sp#38400:
h|std.19200|19200-baud:\
    :sp#19200:
i|std.14400|14400-baud:\
    :sp#14400:

I have tried all combinations from 9600, 14400, 19200 to 38400. What is
really wierd is that my modem can connect succesfully to the modem which 
cannot connect to my modem. In other words, if my modem initiates the
call it is ok, but if another modem initiates the call, it acts as id the
other modem hung up right after it called. TO the other modem I believe
it looks like my modem dropped the line.

In a related problem, another modem (Zyxcel) works fine when my modem 
initiates the call, but when the Zyxcel initiates getty won't pick up the
port unless I am running the ttydfa at 9600. The Zyxcel seems to do better
than the other modem which as I stated cannot even get to a carrier.

I'm pretty sure I have most of the obvious things setup right on my
modem. but there is either something I have wrong, or this modem just
won't work with the NeXT. I'm not sure though that the problem is the
Modem/NeXT interface, as it works fine (it is right now as a matter of
fact), for most cases things are ok. When it doesn't work, it isn't
really interacting with the NeXT (I don't think), it seems to have a
problem mainly answering the phone. I thought maybe it always tried
to be a fax machine when answering the phone, but I am not sure.

Note that I'm not running any software except the nominal NeXTStep and
getty (except for the case of dialing out when I use either kermit or
uucico - both of which work fine).

Thanks for any help
