[ltp] pppd <-> /dev/ttyS14 oops

[Robert Hajime Lanning]

I have a TP 600X with the Lucent modem.  I have been trying to dial my
commserver at work.  It uses chap for authentication.

Has anyone seen this before.

Linux mini-me 2.2.16 #2 Tue Jun 13 23:12:53 PDT 2000 i686 unknown
with the 2.2.16combo patch installed
Lucent Modem driver version 4.27.5.66 with MANY_PORTS MULTIPORT SHARE_IRQ enabled

ls -l /dev/modem
crw-r-----   1 root     uucp      62,  78 Jun 16 16:35 /dev/modem

When the chat script gets a connect and exits pppd logs in syslog:
