I'm trying to setup the dialer and ran into the following problem: First, I ran modprobe, martian modem, and wvdial and it seemed to identify the modem port okay. Next, I tried setting up the dialer with $ sudo nano /etc/wvdial.conf and added ISP information. Lastly, I tried to dial using $ sudo wvdial I got the message "cannot open /dev/ttysmo: no such file or directory" Thanks.
