Hello,
I'm unable to setup the Internet connection... Looks like the problem is in pppd, can you help please?
pppd displays some weird symbols (these symbols are different every time I reconnect) and then dies in 30 seconds:
[user@myhost ~]$ sudo wvdial

^CCaught signal 2: Attempting to exit gracefully...
[user@myhost ~]$pppd error code 16 is:
16 The link was terminated by the modem hanging up.
Looks like pppd have to perform something during 30 seconds after start but it doesn't perform it.
P.S. /var/log/messages:

It looks like pppd is fine, but it's trying to use a device that doesn't exist.
--> Cannot open /dev/rfcomm0: Input/output error
--> Cannot open /dev/rfcomm0: Connection reset by peer
--> Cannot get information for serial port.What is the GPRS device you're using?

These errors occur on _redial_ attempt.
(I have to execute "/etc/rc.d/bluetooth restart" after every wvdial attempt but I think it's OK).
What is the GPRS device you're using?
Samsung SGH-D830 (via Bluetooth).

I would try enabling the debug option with pppd and take a look at the logs it creates to see what's going on.
