RF-PIC16F877A problem

Hi everybody!
I have a problem about RF and PIC16F877A.
In my project I'm sending the data from PC via rs232 (and max232 and atx-34 s) and and receive via arx-34 c and send to the pic from RC7/RX (26th) pin of 16f877a.
I can see the tx sends the data and rx receives the data. But the problem is pic16f877a can't process the data. What could be the reason.
PS: I'm sending ascii data like B.
e.g. data1=getchar();
if (data1=='B')
{
output_high(port_d5);
delay_ms(1000);
Output_low(port_d5);
}

Thanks you...

I am sorry but I am not following you. The pic16f877a is a digital controller. There is no RF function in it. This is an RF and Microwave forum. I suggest you find a microcontroller forum to post your message on.

Thank you man, I am new here
