SUMMARY PPP unable to complete connection

I got three responses on this one.

Andrew Pollock <> suggested that the client machine was
talking PAP and starting PPP as soon as the connection was made, rather than
doing a login prompt. I confirmed that PAP was not running (we're using CHAP),
and the problem was still there.

Joel Turoff <> suggested the resources at Stokely
Consulting (
 These are excellent resources, and I had used them to set up our original PPP
connection (pppd version 2.3.5), but I didn't see anything regarding this
particular problem.

Bill Armand <> suggested manually dialing the system and
trying a \d after seeing the CONNECT, then adding the appropriate number of \d
characters before login: in the /etc/uucp/Systems file. This didn't quite work
but may have something to do with what ultimately did.

In desperation, and thinking that maybe the client was spitting out a login
prompt that was unreadable for some reason, I started to log in with our
connection account ("ppp")... and presto, a login prompt appeared. Some
experimentation confirmed that, once I saw CONNECT, if I sent the letter "p"
four times, the login prompt would appear, and I could log in normally.

I have no idea why this works, but it does. The line on the other end may be
using pulse dialing, rather than touchtone, but I doubt that has anything to do
with it, since I was able to reach the remote modem but not the remote machine
connected to it.

Thanks to those who responded.
