Dear Jason,
Had a chance to look at this this morning, and I found this:
When the dialer map statement does not include the "name HOSTNAME" switch (wher
e HOSTNAME is the name of the dialed host), I got the same symptoms you describ
ed. When this switch was included, the routers negotiated successfully. I'll
append excerpts of a working config.
Hope this is helpful to you.

I am having trouble getting an async dial-up working between routers in my
lab...
The symptoms:
The router will initiate the dial, connect, and pass through the
authentication. The debug shows that the LCP setup of IP completes.
However, I am unable to pass any data across the line and the line will
take itself down at what appears to be a random interval, usually less than
1 minute later.
I am tired and stumped... can anyone assist?
Config:
2511A has a Hayes Optima v.34 attached to line 8, the modem is manually
configured.
2511A is running IOS 12.0.7
2501A has a Hayes Optima v.34 attached to the AUX port, this modem is also
manually configured.
2501A is running IOS 11.0.22 IP Only
I am forcing the dial by pinging the 2501 from the 2511.
