Problems with GPS/GPRS SIM908 shield on Arduino Uno

I followed all the steps for "How to drive the GSM Mode via USB port" on the Wiki.
But all i get on CoolTerm is: . .
My PWR, STAT less are always on. NET led blink on and off.
I'm also providing power using an external power supply. My S2 switch is on the USB side, my S1 switch is on the Comm side. I don't know what's wrong. I'm trying to send AT commands but the module doesn't seem ready for them.

It is very strange. Could you use arduino ide serial monitor to watch the module directly.
When the "stat" on and "net" blink, could you make a phone call to the sim card, the answer is working or power off ? Grey.CC
