Abstract

Conventional bisynchronous communication protocols define a "message" to consist of a sequence of one or more transmission blocks, the last of which is terminated with an ETX (End of Text) control and intermediate blocks are ended with ETB (End of Transmission Block) controls. The bisynchronous communication (BSC) message boundaries generally are significant to host applications. For example, Remote Job Entry (RJE) programs generally equate BSC messages to data sets. Thus, in submitting a "job" input stream, the JCL (Job Control Language) and data must appear in the same message. Furthermore, in many cases, the host response, each message to be followed with an EOT (End of Transmission) by the terminal to relinquish the send role to allow the host to send a response.
