Radio Check
A request can be sent to the radio to determine if it is turned on, on a specific frequency, or within range. The radio will respond with an 'ack' if it hears the request containing its individual ID. The radio can also be programmed to ignore these packets and not acknowledge them. It can also be programmed to perform this acknowledgement 'silently' (the radio user never knows that his radio has been 'pinged').

Famous quotes containing the words radio and/or check:
“England has the most sordid literary scene I’ve ever seen. They all meet in the same pub. This guy’s writing a foreword for this person. They all have to give radio programs, they have to do all this just in order to scrape by. They’re all scratching each other’s backs.”
—William Burroughs (b. 1914)
“cried as he died, fearing at last the spheres’
Last sound, the world going out without a breath:
Too proud to cry, too frail to check the tears,
And caught between two nights, blindness and death.”
—Dylan Thomas (1914–1953)
