/dev/rmodem


hmmm, /dev/rmodem? are you sure thats correct? Its not /dev/modem, or
/dev/ttys0 ? What comm port is your modem on? ttys0= comm1, ttys1=com2,
ect.. Are you sure you have to do a terminal or script based logon, and not a
pap/chap? I'm only guessing here but its a place to start.

this was the message generated and stored in the log file that i have copied.
my modem is on /dev/ttys0--comm1
my login is terminal based

in kppp options, check for modem working ( QUERY MODEM) and the correct port.
