Hi,

I have been trying to connect with a site in Sri Lanka from the U.S.
using 2400 b/s V.22bis modems (Everex 24+) on both sides and am having
problems in connecting.

The remote modem (in Sri Lanka) answers and I hear carrier but sometimes
I don't get a CONNECT message, and sometime I do get a connect message
but can't transfer any data (not a single byte). This happened both with
MNP4 on and off (MNP5 was always off).

The connection appears OK, a bit noisy and with satellite delays and echoes
but voice communication is no problem.

O.K., the question is: What am I doing wrong? What should I look out
for and what parametes of the modem should be set for this type of
circuit. A side question: What does the guard tone do? Should I turn it
on?

Thanks for your help,

Gihan
