Keylock for Communications Priority

A priority keylock switch provided at a first communications terminal, is activated to grant another communications system (terminal or central processing unit) priority in specifying the communications direction and sequence.

Activation of the priority switch enables logic circuitry at the first terminal to inhibit the origination of any communications actions at the first terminal. The other system, therefore, may send data to the first terminal, or cause data previously stored on a media at the first terminal to be transmitted to the other system.

The priority switch is activated to prevent the first terminal from interrupting the transmission of messages from the other system to the first terminal, to require communications to be effected at the most advantageous time from the standpoint of line or other system usage, or to insure security of the data available for transmission at the other system but not intended for transmission to the first terminal.
