[sci.electronics] Info on 1200 baud internal modem wanted

marcus@illusion.UUCP (Marcus Hall) (02/02/88)

I purchased an IBM PC type 1200 baud internal modem at a hamfest yesterday.
Unfortunately, the documentation turns out to be for a different type of
modem card (I guess this isn't too much of a surprise.)  Anyhow, I was
wondering if anyone out in the net would be able to help me figure out
how to configure this thing.

There are three jumpers (straps) on the card and a six position DIP switch
that faces the back of the card.  The jumpers are labeled J5 (near the back
of the card, in front of one of the TELCO jacks), J6 (bottom of the card,
above left side of connector), and J7 (botton, above right side of connector).
These jumpers are all labeled "A" for the left connection and "B" for the
right.  The DIP switches are just collectively labeled SW1.  The board is
silkscreened "OMNITEL 1200 PC3 REV E".  There is an FCC sticker that also
contains the OMNITEL name, but no address of the company anywhere that I can
find.

I don't anticipate any problems once I get the card configured for the proper
address.

I imagine that this is a clone of some other modem, and perhaps someone out
on the net has either this make or the "real" card that this is a clone of.
If anyone recognizes this, please send me mail on how to configure it.  If
anyone recognizes the company "OMNITEL", I can call them and possibly get
ahold of their documentation.  Anything would be helpful (Trial and error
is possible, there aren't many combinations, but that's really a pain!)

Since this is obviously not of general interest to the net, please just send
me mail.

Thanks!
