Abstract
A line adapter unit working in conjunction with a microprocessor which serves to handle data transmission using the bit oriented protocol mode. The microprocessor can select any one of a plurality of input-output circuit units which provide specific control of communications to/from remote data terminals or data sets. The microprocessor can select and control various components of the input-output circuit means such as regulating the timing means and setting up command structures for controlling the type, the direction, and the conversion of serial bit data. Likewise, each component of an input-output circuit unit may request service via an interrupt to the microprocessor and receive a command or response required for further operations. Each input-output circuit unit is provided with a dedicated memory area associated with a given data communications line. An automatic calling unit output register is also provided which can receive signals from the microprocessor which can be used for automatic dialing of the remote data sets.
