RSTS/E Communications Link Via an Asynchronous Multiplexer

摘要

The Biology Division of Oak Ridge National Laboratory had an immediate need for a communications link between two PDP-11 computers, to allow timesharing users to transfer disk files between systems, while waiting for software development on a more general communications system. A program was written to use one line of a DZ11 asynchronous multiplexer on each computer for communications, and thus make a simple hardware connection with a RS232C null modem possible. A second program was written to permit easy user access to the link. Development, implementation, and performance of the programs are described. (ERA citation 05:039209)
