Title: Line adapter for data communication system
IPC: G06F13/22
Filed: 1969-08-18
Abstract: 1,240,626. Data transmission. BURROUGHS CORP. 18 Aug., 1969 [30 Aug., 1968], No. 41120/69. Heading G4A. Apparatus for transmitting digital data to and receiving digital data from a plurality of remote stations 12 over a common line, comprises an addressable memory having a plurality of polling messages stored therein at predetermined addresses, each polling message including coded characters for identifying a particular station and signalling a request for data, means for transmitting the characters to the stations, means responsive to the transmission of an end of message character for terminating the transmission and means responsive to a no-message character or characters received from the remote station, whereby another polling message is transmitted to the stations. A computer 10 is connected to line adapters 16 by way of a Data Transmission Terminal buffer unit 14 which includes the addressable memory. Data sets 20 provide serial transmission on standard telephone lines by a modulated carrier. The adapter translates the 6-bit computer code to a standard ASC11 seven-bit code for transmission by means of a code set (Fig. 5, not shown). The unit 14 has its memory loaded with the polling messages and then follows the routine shown in Fig. 4 whereby each polling message is sent in sequence until a message from a remote station is received, which message overwrites the polling messages. Each polling message comprises an EOT character which ensures the adapter 16 is cleared, two address characters which identify the station, a POL character, and an ENQ character which specifies that a response is required. The adapter looks at the first character at 54 and if it is EOT, sends it to the remote station at 56. If however a Group Mark (GM) is the next character then an interrupt is generated. The two address characters are transmitted and alert the terminal, followed by a POL character which causes the adapter to enter the poll state (68). If an ENQ character is detected the adapter enters a receive state and waits for a response from the station. If no response occurs within two seconds an interrupt is generated (78). Normally the station sends an EOT character (negative response), the character is discarded, and the adapter transmits the next polling message unless there is a Group Mark. One type of Group Mark causes the poll to be repeated. If characters are received they are stored in the buffer by over writing the polling messages until an ETX or EOT character is encountered (100, 102) which results in interrupt and/or reset as indicated. The various operations are controlled by clock pulses from the computer 10.
