     I noticed something similar with pppd. I'm new to Debian, I'm just
trying to install and configure it these days. At the moment I'm writing from
and old Slackware, under which (pppd 2.1.2) I left the following lines as a
remark in my ppp-connect file: 

# pppd connect 'chat -v \
#           "" "ATZ" \
#           OK "AT&FE1V1Q0L0&C1&D2&K3S11=55S38=0S95=2" \
#           OK ATL2X3DT220792 CONNECT'
#
# Without the long second string to the modem, re-connection succeeds,
# otherwise pppd fails for any re-connection after the first, waiting for 
# answer from the modem and then claiming something about SIGHUP, till 
# reboot.

I can't dial and connect but the first time if I also want to send the longer
string "AT&FE1V1Q0L0&C1&D2&K3S11=55S38=0S95=2" as modem initialization beside
ATZ.  (Here /dev/modem is a symbolic link to /dev/cua1.)
