When i connnect the phone to the PC and test the cable with hyperterminal, there is no response thats no ERROR or OK, what could be the problem,
I used the following commands at the hyperterminal,
AT
I expected OK or ERROR but its blank
AT+CPIN?
I expected +CPIN? READY OR ERROR but blank also
Could it be the cable?, PC or settings of PC, pliz guide me.
regards
dumato
