ABSTRACT:
A communications adapter for interfacing a transceiver and a line including a synchronous receiver-transmitter programmed by a controller to operate the receiver-transmitter in different data formats during a single frame transmission to or reception from a transmitter/receiver and including logic programmed by a controller for controlling the operation of a transmitter/receiver on a bit level to halt the transmitter/receiver during programming changes of format between and during a frame. For frame transmission to a transmitter/receiver, the receiver-transmitter is programmed for a first portion of a frame for a number of bits per character as a function of transmitter/receiver and line protocol and for second portion of a frame for a number of bits per character as a function of line protocol. For frame reception from a transmitter/receiver, the receiver-transmitter is programmed for a number of bits per character as a function of line protocol and a synchronization pattern as a function of line and transmitter/receiver protocol.
