This is strange and it has happened with both an internal ISA modem (set up for com1-irq4) and an external modem(US Robotics sportster). Post physical intallation ... boot up (RH 7.1w2.4.18 kernel) ...KUDZU finds and configures the modems. When I use RH dialup configuration it does NOT find the (in/external) modem. (yes I've gone through this procedure with KUDZU disabled and got the same results) I continue to enter my ISP info. and manually set up the modem (/dev/ttys0). I then try using RH ppp dialer ... it will not dial. But if I go back to RH dialup config, on the accounts tab and use debug mode the modem works fine ...dials out and connects. I've tested the connection by FTPing to various sites. Initially, thinking something might be wrong with the installation ... I removed and reinstalled the rp3 and wvdial rpms. The situation remained the same.
I haven't got a clue on how I can remedy this. I've looked through some How To's but could find nothing directly
related. Please help

Hi.

I've been on a steep learning curve with RH scripts, pppd, chat & wvdial while connecting to adsl, SDI or other devices which have static numbers.
The RH scripts basically take data from ifcfg-ppp0 and use pppd to call wvdial which calls chat to do the port initialisation, handshaking and authorisation before dropping back to a daemon. There are a lot of places where it can turn turtle...
My suggestion is to start with the log files to see what RH reckons is the prob.

Try tail -f /var/log/info in a shell window, then start the dialler programme you want to use. Keep an eye on the log messages and see what it can't do.
Check you have /dev/modem as a softlink to /dev/ttyS0 or ttyS~ whatever port you are using.
ls -l /dev/modem
If not, in a shell window go
cd /dev
ln -s ttyS0 modem
This is a place to start... next thing is to dissect your conf files.
Regards,
Peter.

Thanks, your suggestion sent me right where I neede to be. The log stated: ...warning: Section [Dialer sprint_1] does not exist,(in wvdial.conf). I vi'd /etc/wvdial.conf ... the Dialer entry was [Dialer sprint1] (no underscore!!!). How that occurred I couldn't tell you.

Thanks Again
