You would need to put 'a' into the TXREG, but other than that, yes...
I am not familiar with RealTerm, but it seems some other people have had issues doing this with it... perhaps you could try TeraTerm?
Serial comm using pic16f877a....

Is this OK, after dowing this also it is not displaying data on terminal window..?
post your code...

}In this tera software how to set com 5 or 20 there is no option?
OK, it has detected automatically but nothing is typing on terminal window why???
did you set up the serial port?
yes 9600 com 5
One thing more i am unable to type on terminal window from keyboard, why?
Your build doesn't show warnings, right?
Is there anything showing up on your terminal window?
Can you take a picture of the circuit?
yes no warning ..
nothing even i can't type on it..
i am using the same circuit posted in post rx to tx and tx to rx and 5v from USB connected to uC
I want to verify your connections... I can't do that with your art.
OK, then how to have circuit i mean what part i show to u??
actually i am using this board for many time for testing and using like led display controller....
everything work fine on board!

If that LED is connected, try turning that on when the program starts...
Do you have a MCLR resistor? I don't see one....
yes i have 4.7k with switch to reset also all work fine!!
Is this fine??

}Ok, i have done LED is glowing but nothing is coming on window, why??
Now what to do??
i have that 2.4Ghz module should i use that for testing, how??
