Don't have a serial port attached to my CPU, so I am using a cable connected to USB port which in turn is connected to a USB to Serial converter
which in turn in connected to the GPRS modem.

Scanning your serial ports for a modem.
Modem Port Scan<*1>: S0 S1 S2 S3 S4 S5 S6 S7

ttyUSB0<*1>: ATQ0 V1 E1 -- failed with 9600 baud, next try: 115200 baud
ttyUSB0<*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?

Have tried using minicom
. It doesn't show any characters as an output of the modem.
This modem has been tested on a Windows machine and it does respond well
The ONLY fields I have edited in wvdial.conf are Modem and Baud.
