I am trying to access my GPRS Modem (Sierra Wireless AirCard 710 -
PCMCIA) programatically. I am facing two problems.
1. The first time I send ATD*99#, I get a CONNECT. Soon after I get a
NO CARRIER. Subsequently whenever I send ATD*99# I get an ERROR.
Cannot get any reason even tho' I have AT+CMEE=2. AT+CEER also does
not return a reason back. What step am I missing? I tried putting an AT+CGATT=0 and AT+CGACT=0,1 but even tho' I get a detach and a PDP
Context deactivation, ATD*99# still returns ERROR.
2. After CONNECT, the modem sends LCP packets and I am succesfully
able to negotiate LCP. The modem does not send any IPCP or any other
packets after LCP is UP. So I send out an IPCP packet, but the modem
does not respond. Soon after it returns NO CARRIER. What am I supposed
to send after LCP is ACKed?
I am willing to try all possible theories so please send any
suggestions that u have.
Thanks,
