I’m Using a WAVECOM WMOD2

I’m using Hyper terminal to connect the Modem, iI set the Modem at Mexico with Telcel carrier. And i set the port settings as  
Bits Per Sec : 9600  
Data Bits : 8  
Parity: None  
Stop Bits: 1  
Flow Control: None

Moreover i connected the modem with a USB to my PC via a USB-Serial convertor, because i don’t have the serial port.

the output of the modem is shown below. [size=150]Using USB- Serial Convertor[/size]

This is the output when i connected directly to a serial port of some other system with same port settings.
