Abstract
A system for detecting the presence of mail in a post office box. A post office box holder calls a telephone number which accesses a computer. The computer contains data representative of the presence or absence of letters in a plurality of post office boxes. If the box to which the caller refers is occupied, a series of tone pulses is transmitted to the caller by a tone generator under the direction of the computer.
