[comp.dcom.modems] Accessing Prodigy from a Telebit T1000

spsisira@sdrc.UUCP (Sisira Jayasinghe) (01/16/91)

I am trying to access Prodigy service from a T1000. Since Prodigy
support maximum baud rate of 2400, I changed the S50 register to
3 ( ie. 2400). When I run Prodigy, it dials out and get the modem
signals but when it tries to exchange signals program issues
communication error. I tried Prodigy support service they could not
figure it. May the person I spoke to may not be that experienced.
So, I decided to bring the problem to TRUE experts of the world.

If anyone successfully access Prodigy from a Telebit modem, I am very
grateful if you tell me how to resolve my problem.

Thanks in advance.

Set the T1000 to Conventional Command Mode (CCM).  TURN OFF MNP!  This is
what causes the modem error, the majority of the time.  Once you're
in CCM, set:

AT~S51=2S66=1S95=0

This sets NO MNP and a locked interface of 2400 bps.  S50=3 (V.22bis-2400 bps
ONLY) may not be needed.  Add this to the above string if it is needed due
to more modem errors.  This set-up worked for me, but I was very disillusioned
by the quality of Prodigy.  I'm having an easier time convincing my computer
banking service to go V.32 than getting a hold of anyone who'll listen at
Prodigy.

Hope this helps!
