ABSTRACT:
A data communication system in which a host data processing system is responsive to an automated sequence of data processing request signals from a remote data processing system. The remote data processing system includes a means for generating and storing in a nonvolatile read/write memory a log on signal which initiates the communications and causes the host system to be responsive to the remote system, a plurality of data processing request signals specifying operations to be performed by the host system and a log off signal for terminating the data communications. Special data processing request signals may include a predetermined delay before transmission of the next data processing request signal by the remote system or may require the host system to transmit a predetermined response signal in order to enable continuation of the sequence of data processing request signals from the remote system. The remote system may be constructed in order to inhibit transmission of the next following data processing request signal until a predetermined time after the last received signal from the host system. Preferably the remote system includes a memory for storing signals received from the host system in response to its data processing request signal and means for operator review of this memory after log off.
