Byte-oriented line adapter system.

摘要

A line adapter system for handling byte-oriented data transfers between remote data terminals and I/O subsystem. Working in conjunction with a controlling microprocessor, the line adapter provides input output means for regulating the baud rate of transmission to/from a remote terminal and for the timing and protocols required for both synchronous and asynchronous data transmission. The microprocessor may address and control various of the timing elements and byte to bit transfer means of the input/output circuit means. Likewise, each of the elements of the input/output circuit means may request service from the microprocessor for further detailed instructions.
