Abstract
A method and system for controlling a terminal includes a receiving unit in communication with the plurality of terminals receiving a command signal and converting the command signal to a serial port control signal. The receiving unit formats the serial port control signal to form a formatted signal. A terminal device receives the formatted signal, recovers the serial port control signal from the formatted signal and controls a terminal device in response to the serial port control signal.
