modem not dialling under redhat 7.1

I am using KDE (Redhat Linux 7.1 installed on a Toshiba Tecra 520CDT laptop) and used the Kppp configuration tool to setup dialup internet access using my US Robotics external 56K modem. While the modem was successfully detected with Kpp config tool I cannot dialup with it. The Kppp log shows an ATZ signal being sent and not being responded to. As a result my Kppp internet dialer hangs with a message "INITIALISING MODEM".
I know this modem is compatible with Linux-like systems as I've used it successfully with FreeBSD and this Linux system correctly detected it as new US Robotics modem hardware when rebooting after I plugged it in after the Linux install.

Is your modem defined in KPPP as /dev/modem or /dev/ttys[0,1,2,3]? /dev/modem is just a link to one of the others, but it's better to just use the actual device file. So, if KPPP is using /dev/modem try changing it to the actual device file. Hope that helps.

Compared to my experience with FreeBSD setting up ppp dialup with Redhat 7.1 and Kppp is pretty simple. I'd already setup my modem on /dev/ttys1. Each time I tried a port I got Kppp to query the modem on that port, so with ttys1 it queried the port correctly. I've done everything else that the documentaion says but no luck. Someone even suggested I use RP3!?! I'm not sure what they were implying here.

i've had a similar problem with kppp - i ended up just using wvdial, which works fine. if you want to keep using kppp, try upgrading to a newer version.
