Dear everyone,

I would ask some questions about GPRS connection.
Because when I use PC to connect GPRS Module.
I can use AT Command to control the Module,
Ex. AT+CGDCONT, AT+CGATT, AT+CGACT...etc.
when I send the ATD*99# to the Module,
the Module will response A PPP LCP Configure-request to PC and get into the Data Mode.
But when I resend the PPP LCP Configure-ack to the Module, It don't respoense any message to the PC.

Would you know how to get the connection between PC & GPRS Module?

Thanks!
