Mark: You can use them for sending "control" signals, which the FCC treats very differently than "data" signals. Control signals are sent when someone presses the "disarm" button on his car-alarm transmitter, or activates his automatic garage-door operator, or when the transmitter on the front door of his house sends a periodic "the door's still closed" transmission to his home security system. Data signals involve things like wireless printer ports, cordless telephones, continuously-updating telemetry from a sensor, etc. -Andy === Andrew Warren - fastfwd@ix.netcom.com === === Fast Forward Engineering - Vista, California === === === === Custodian of the PICLIST Fund -- For more info, see: === === http://www.geocities.com/SiliconValley/2499/fund.html ===
