    These are similar to the 433MHz modules sold by Parallax (www.parallax.com/detail.asp?product_id=28180).
    Any serial driver (like FullDuplexSerial) should work. Limit the Baud to 4800.

    Your main problem will be to ensure reliability. There's no error checking nor is there any checking for the presence of a signal.

    With no received signal, the driver will see a string of zero bytes, possibly with a byte or two of "junk" during the transition from no signal to a received signal. It's common for a wireless transmission to begin with some "sync" characters ... something with several zero and one bits. If there's a lapse in transmission of more than a few character times, the transmitting program will usually send another sync character before beginning the actual data.
