I followed eveyr single instruction line-by-line and everything was going smoothly. But when I did $sudo wvdialconf the following messages were displayed: root@ubuntu:/home/elven# $sudo wvdialconf Editing `/etc/wvdial.conf'. Scanning your serial ports for a modem. ttyS0<*1>: ATQ0 V1 E1 -- failed with 2400 baud, next try: 9600 baud ttyS0<*1>: ATQ0 V1 E1 -- failed with 9600 baud, next try: 115200 baud ttyS0<*1>: ATQ0 V1 E1 -- and failed too at 115200, giving up.

Sorry, no modem was detected! Is it in use by another program? Did you configure it properly with setserial? Please read the FAQ at http://alumnit.ca/wiki/?WvDial When trying to dialout: root@ubuntu:/home/elven# $sudo wvdial --> WvDial: Internet dialer version 1.61 --> Cannot get information for serial port. --> Initializing modem. --> Sending: ATZ --> Sending: ATQ0 --> Re-Sending: ATZ --> Modem not responding. root@ubuntu:/home/elven# I wonder what could be causing the serial port problem, is there the possibility there is another driver messing it? I did a few attempts to make things work previously.
