Re: GSM with 8051

what about the pop port.

what is pop port?

how to use this with hyperterminal

Connect your GSM Mobile to PC COM1 with your GSM Data Cable
Run Hyperterminal, setup COM1 property as :
Bit per second 9600 (Buad rate)
Data bits 8
Parity bit None
Stop bit 1
Flow Control None

Click CALL icon, key in AT <enter>, if the connection is OK your GSM Mobile will answer OK

try another baud rate is this is connection problem

Nokia 5110 is best for doing this
its serial port is taken out on connector
if you need I have working source code to interface Nokia 5110 with philips P89C51RD2

Re: GSM with 8051

ok i have a dlr -3p cable which has a rs-232 db-9 female connector
it works well on hyperterminal
now the db-9 connecotor i have taken two wires from the rx and tx of the 8051 thru the max 232 and then in the tx and rx of the db-9 (of the dlr-3p)
it should work but when i connect the gnd to pin 5 of the db-9 the controller starts to funtion abnormally plz if anyone has interfaced the 8051 with dlr-3p-- nokia 6310 send me the diagram ,i am sure the programming is not the problem the problem is which of the pins of the db-9 is to be connected to what , thats what i cant figure out , i am sure it has also something to do with rts right? plz answer
