Abstract

A general purpose data control terminal which permits multiple terminal control. The terminal is programmable thereby permitting compatability with a wide range of communications systems. The unit is microprocessor based and includes a keyboard, and display, and utilizes acknowledge and retransmission logic for improved reliability.

Claims

1. In a register modelled communication system for data and voice communications, having at least one primary station and a plurality of remote stations, each remote station having a predetermined station address, and each station adapted to transceive data signals including at least a command data packet, a data terminal for the primary station, comprising:

means for entering a remote station address;

generating means, coupled to said entering means, for generating a data command packet containing at least an operation code, an argument and said remote station address, including means for transmitting same to the primary station;

means for receiving a remote command data packet from the primary station, including at least one register means for receiving the remote operation code and argument;

display means, coupled to said receiving means, for displaying the predetermined station address from said remote command data packet; and

means for executing the remote operation code, from said remote command data packet, in cooperation with said argument.

2. The data control terminal of claim 1, which further includes means for automatically acknowledging receipt of a remote command data packet.

3. The data control terminal of claim 1, which further includes means for automatically re-transmitting a command data packet, for a predetermined number of times, upon failure to receive a remote acknowledge command data packet.
