	I have a question that someone on the net may be able to help me 
with.  I have a requirement to "network" two computers via a telephone
circuit, a 3002 type.  These computers "talk" to each other using their
networking ports and using TCP/IP.  We went out and leased a pair of 
Gandalf LDM419's, we are running the modems in Asynch, single channel at
9.6Kbps.  They don't work, that is to say I am unable to pass data in the
TCP/IP format through them.  We have them set up in the computer room with
a short piece of phone wire between them.  This eliminates the phone circuit
as a possible problem.  The vendor sent his tech out to "check us out" and
he verified that we had the modems configured properly.  The really strange
part is that a pair of LDS120's worked fine.  THe vendor indicates that the
LDS'S are "bit transparent" .   I have a lot more information concerning our 
set-up and the computer equipment, but I won't tie up the net trying to ex-
plain it all.  If anyone has modems that they are currently using to pass data
in TCP/IP format or can explain why ours don't work, please send me mail or
give me a call.

						Thanks,
