<p>High-speed communication between a computer and a peripheral device using low-speed serial and parallel interfaces is achieved by a protocol which sends and receives information through data input, data output, control and status circuits. Extremely high-speed communication using conventional RS-232 serial ports and parallel printer ports is made possible. Communication circuit status may also be interrogated by a device to allow automatic reconfiguration to various serial and parallel communication channels.</p> |
