Hi,
I have interfaced sim300 gsm modem and pic16f690 via uart.
I am receiving only 0x0a even if sim300 sending so many string like
"OK"
"READY"
What could be the reason?
Thanx in anticipation.
Lokesh

Without more information its very difficult to identify what the error is. Post more information - your PIC, the way your have configured the UART, additional hardware connected to the modem and the PIC, etc.
What is the UART speed on the modem? Have you configured the PIC for the same speed?

I agree, more info would be needed to accurately identify the problem, but I can offer you a theory for you to try out.
0x0A is the new line character, which certain protocols use to identify the end of a command.
This makes me think that maybe each time a new character is received it overwrites the previous one in the buffer, then when you come to read it all you see is the final character.
