ABSTRACT:
In a data transmission system, for communicating messages between a base station and a plurality of mobile stations, each mobile station includes a radio frequency transceiver and a programmable data terminal for sending and receiving predeterminedly formatted digitally encoded messages. A keyboard subsystem and character display subsystem are controlled by a programmable microprocessor subsystem which also processes received and transmitted messages. A transmit and receive system clock interrupts the operation of the microcomputer to process messages. The messages include a cyclical redundant check byte as well as a control number byte. Characters which are not editable blink. A terminal status display line is provided and a message received character is also provided. The system sets the system clock period to be the same for all data rates. Automatic restart of the system is provided as well as a means for detecting and generating a pseudo-random message preamble. Cursor positioning, memory interchange, and display keys are provided. Receipt and acknowledgement of various types of messages are also provided.
