just tried your code on a 16f648a , works perfectly from my pc usb through tty converter to pic , you must have polarity of signal screwed up.

The difference between 2389 and 2400 would not seem a big deal, it only 0.5% (if my maths right, which is unlikely)

I traced out the board and realized another component sitting between the board input and PIC was inverting the signal. The board is being re-purposed from a different use so I was able to bypass that and everything is working as expected. Thanks
