Thanks alot for the reply
I am stuck up in dis problem pls help me out with dis
the problem is :
TO SIM900:
PC-> Hyperterminal -> ATD9738XXXX18;<enter> : i get a call
8051 -> same command : not getting a call
have sent a carriage return after the command (0x0D)
used realterm to check if the data coming out of 8051 is right . it is perfect when i compared wat i manually send and the command coming out of the 8051.
SIM900 sends OK to the hyperterminal after the command
but it exactly sends <CR><LF>OK<CR><LF>
i didnt write a routine to recieve data in 8051. will that be a problem?
Next i did write a code to recieve and parallely as i recieve data i have to display it on the LCD(16×2)
but i get garbage values.
is my SIM900 not responding because i m ot accepting the OK or is there something else . I am seriously not able to understand where the problem
can u pls help me out with dis
Thanks in advance
