The purpose of the modules was to replace the ones I used to get from Aurel or other pin compatible from Asia. I managed to make it cheaper and equally sensitive fore the use onGarage door openrs or other similar short range devices. Freq. is 433.92MHz and sensitivity around -105dBm for 4KHz BW or -109 for 1KHz. Including the SAW filter in the antenna path. Chip used T5744 and on the newer ones TDA5200 with 3db less.

Well, I still believe it is one of the best cities for the advatage of combining Sea and Mountain in the reach of your hand. Unfortunately, people deserve the leaders they vote for...

Now on the subject, I think you must give a try to the easier Darrel's Instant Interrupt and when interrupt happens, go there and see if the character was the ! or any other usefull data.

In this case you need the USART of he PIC and the Hserin command. The code will not spend much of the time waiting for the character as Melanie stated, it will be done on the background leaving the main routine to do what is supposed to do.
