Abstract:
A system providing for improved local and remote control over operation of a tape reader. The controls being operative to selectively initiate and automatically terminate both the reading and omission of data, with the omission operations being effected at a higher rate than the reading operations. These controls also being operative to automatically inhibit reading operations for various time intervals when the unit is supplying a teleprinter and particular mechanical commands are being executed by the teleprinter.
