Hi Kevin,

Yes, I have already tried it on slower speed (300 bps) and it works most of
the time (not all the time).  I am very sure that the problem is not whether
the correct data is transfered.  I look at the data inputted into the Serial
Rx of the 16F628, and the data is correct (very sure!).  It just doesn't
trigger the interrupt or something like that to let the F628 knows that
there is serial data coming.

I did try outputing TX to my PC serial port.  This works PERFECTLY!  So, I
am very sure that my RF "interfacer" chip is doing its job.  Thank you very
much.

Rudy

Hi Rudy,
I have tried serial IR to a PIC16F628. It worked well after I slowed down
the TX/RX speed. I doubt you are having this problem with RF, but you could

try and slow down your TX/RX speed, like 2400.
The I/O pin on the PIC12C509A should have no problem driving the F628 pin.
Also, you could try outputting the TX to the RX on your PC serial port.

Good Luck,
Kevin
