#100259 - RF links pose challenges, but anyway...
Responding to: Manoz Joshi's previous message
Did the receiver output look like it would be compatible with a UART (i.e., noise-free) -- implemented in either hardware or software? The only advantage to a bit-banged UART is that you'll be able to tailor it with some kind of noise filtering algorithm.

Manoz Joshi said:
Since I don't have plenty of money and I prefer to test it with bit-banging (software UART) in order to see if it work better.

Since you're seem set on asynchronous NRZ, there's plenty of bit-banged UART code to be had by searching the net. Philips and Programmer Heaven for starters.
