Abstract: A DATA PROCESSING SYSTEM HAVING A MAIN DATA PROCESSOR AND A PLURALITY OF REMOTE TERMINALS EACH HAVING DATA PROCESSING CAPABILITY. THE MAIN OR CENTRAL PROCESSOR IS COUPLED IN A POLLING ENVIRONMANT TO THE VARIOUS TERMINAL PROCESSORS VIA A COMMUNICATION LINK. COMMUNICATION OR DATA TRANSMISSION OF EACH OF THE VARIOUS PERIPHERAL OR TERMINAL PROCESSORS TO AND FROM THE CENTRAL DATA PROCESSOR IS CONTROLLED BY SEPARATE LINE DISCIPLINE PROCESSORS. A LINE DISCIPLINE PROCESSOR IS COUPLED AND RESPONSIVE TO THE RESPECTIVE DATA PROCESSOR AT EACH REMOTE SITE. THE LINE DISCIPLINE PROCESSOR AT EACH REMOTE TERMINAL EDITS AND ASSEMBLES THE INFORMATION TO BE TRANSMITTED AND IDENTIFIES, EDITS AND ASSEMBLES INFORMATION RECEIVED AND PERFORMS OTHER TASKS RELATED TO THE COMMUNICATION FUNCTION THEREBY PROVIDING MICRO-PROGRAMMED LINE DISCIPLING.

Abstract: A REMOTE TERMINAL STATION CONNECTED BY COMMUNICATION CHANNELS TO A CENTRAL PROCESSOR FOR THE COMMUNICATION OF ALPHA AND NUMERIC INFORMATION. THE TERMINAL STATION IS CAPABLE OF BEING OPERATED IN ANY ONE OF THREE INDEPENDENT MODES. THE FIRST MODE IS ON LINE WITH THE CENTRAL PROCESSOR WITH AN OPERATOR ENTERING DATA INTO THE SYSTEM AT THE TERMINAL STATION. BY PROPER SELECTION OF OPERATIONAL KEYS, THE CODE TRANSMITTED BY THE TERMINAL STATION IS EITHER ASCII OR HAMMING. THE SECOND MODE IS ON LINE UNATTENDED WHEREIN THE TERMINAL STATION "ECHOES" BACK TO THE CENTRAL PROCESSOR ALL INFORMATION RECEIVED BY IT. THE THIRD MODE IS AN OFF-LINE MODE OF OPERATION WHEREIN AN OPERATOR CONTROL STHE INPUT AND OUTPUT OF THE STATION. A RECIRCULATING REGISTER OPERATING ON A TIME SHARING BASIS IS USED FOR SYNCHRONIZING THE OPERATING SPEED OF THE TERMINAL STATION WITH THE SPEED OF TRANSMISSION OVER THE COMMUNICATION LINES.
