ABSTRACT:
A communications control system for enabling a small computer system, such as a personal computer, to emulate a terminal and thus to communicate with a remote system. Incoming data from the remote system is entered into a circular buffer on an interrupt basis. The communications control system alternately scans the circular buffer for newly entered data and the keyboard for operator generated messages. Any control characters are decoded and appropriate actions taken. Received alphanumeric characters are stored in a display memory for video display and in a system RAM for later retrieval and study. The display memory is optionally loaded in an intelligent wrap mode in which words are not broken on wrap around or a non-wrap mode which preserves the columns of the data as originally received. Scrolling controls enable the operator to enter a desired portion of the data stored in the system RAM into the display memory for viewing in either wrap-on or wrap-off modes. This invention also provides control of data transfer to and from the received line memory and local peripherals. In the preferred embodiment, the system is embodied by a plug in ROM module used with a compatible personal computer.
