Serial Modem Pavilion 8765C

I've loaded Redhat 7.2 and am trying to get a US Robotics Sportster 56k external modem to work, with no luck.
error 603: dial-up networking was unable to comlete the connection.

Any help would be appreciated.

Hello,

With serial modem, you should normally have no problems.

Therefore, here are 2 tips :

-> Check the permissions of the modem device file (/dev/ttyS0 or /dev/ttyS1 or /dev/modem).

-> Edit /etc/ppp/options and add a line with the single word "debug". Try another connection, then go to /var/log/messages and look at PPP or PPPD errors.

Good luck.

Re: Serial Modem Pavilion 8765C

Are you using mgetty? What do you have for a modem init string in /etc/mgetty+sendfax/mgetty.config? Have you tried turning on the loudspeaker so you can hear the call progress? Are you sure it has dialtone? Do you hear it dial out? Does the other end answer and try to train up? (have you verified there is a modem on the other end of the circuit by dialing it yourself?) Have you turned on the debug options in the /etc/inittab where you call mgetty?
