Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
160 words
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.
