PPP has nothing to do with ports. It's enough if your mobile phone knows the port number. Oh, and besides mgetty you need a ppp daemon, too. I suggest you read some appropriate documents (like the Linux PPP-HOWTO). Regards Joerg -----Ursprüngliche Nachricht----- Von: manish [mailto:[EMAIL PROTECTED]] Gesendet am: Donnerstag, 16.
