Hi!
When I try to PPP to my ISP I get the following message in /var/log/messages:

Connect: ppp0 <--> /dev/cua0
Serial line is looped back.

I have linked the "modem" with an ln -s to cua0 and I can use minicom and works just fine, but when I try to pppd with all the script that follows after that I got the message.

Hope this informations is enough

Hi,

Could it be that your modem has no connection to the other end at the moment your pppd gives that errormessage? If your modem is offline it's in command modem, which means that all input is indeed echoed back. You will need to connect your modem to your ISP first (using a chat script), and then start pppd. You can let pppd fire up the chatscript with the connect option. For test purposes, you can connect to your ISP using minicom, login and exit minicom without hanging up. Then fire up pppd.

Alex.
