I am trying to connect using a usb cable. The phone is recognized under "Network Center" as an E71. That is about as far as I can get.
wvdial is installed. Although the phone is recognized as above under "Network Center", this is what I get:
Scanning your serial ports for a modem.
ttyS0<Info>: Device or resource busy
Modem Port Scan<*1>: S0
ttyS1<Info>: Device or resource busy
Modem Port Scan<*1>: S1
ttyS2<Info>: Device or resource busy
Modem Port Scan<*1>: S2
ttyS3<Info>: Device or resource busy
Modem Port Scan<*1>: S3
Sorry, no modem was detected! Is it in use by another program?
Did you configure it properly with setserial?
Since I am not an expert in Linux and not exactly knowing what setserial is all about, I have left it at that, as of now.
