Gprs Connection Using At Commands In Hyperterminal

[nagabalaji1988 0]

Dear All,

I am trying to do an GPRS connection using AT command in Microsoft Hyperterminal. I am using Nokia 7210 supernova and using Aircel Connection.

I tried the following to do GPRS connection

AT

OK

at+cgatt=1

OK

at+cgdcont?

+CGDCONT: 1,"IP","aircelgprs.po",,0,0

OK

atd*99#

CONNECT

2}#}$À#}!}$}%Ü}"}&} }*} } g}%~

When i issue the command atd*99#, the mobile shows "E" symbol to indicate the GPRS connection. The mobile or hyperterminal doesnt show anything. How to analyze ~ }#À!}!} } }2}#}$À#}!}$}%Ü}"}&} }*} character and how to proceed further?

Please guide me.

Thanks in advance
