After running ppp and exiting and at some other times, my serial
line to the modem seems to get into a mode which ppp cannot
access through using chat. This is always rectified by running
minicom and exiting. I don't know if it is the modem or the line
that is left in a strange mode. I suspect the line because my
ppp-off-dialer executes an ATZ. I once saw a script that called
a serial line initialization program as part of the ppp dialup but
didn't note it and couldn't find it again or find the program at
or the script at the time. I suspect the answer lies there. Until
then I clear it by running minicom which is of course inelegant.
Does someone have a quick answer?
