Need help with the Parallax 433 MHz receiver and transmitter

I have purchased the 433 MHz receiver and transmitter from parallax. I am running two basic stamp 2 boards, with one having the receiver on it and the other having the transmitter. I have tried to run the sample programs on the data sheet to ensure that these components are working correctly. To my knowledge they are. My question is regarding the SEROUT and SERIN commands. If I just want to send a byte of data across, how do I do that? The project that I am working on is such that the transmitter on one board gets activated by a timer and needs to send an activation signal to the other board via the receiver to trigger some functions on the second board. Can anyone help me out on the coding of how to send that signal??? I know that I need to run a separate program for the receiver and a separate one for the transmitter. Any help and/or suggestions is welcome and appreciated.

The example code from our website should show you exactly what you need to do. That example is ending a block of text, but it could be a single packet or byte of text. The program uses a header/preamble and CRC Checksum to verify the correct data was received on the other end, but other than the overhead you could send a single byte.
