Interfaces
The plotters operate with a variety of computer systems through either the serial, RSĆ232ĆC
port or the parallel, BiĆTronics, extendedĆcapability port (ECP).
An autoswitching feature enables the plotter to detect from which interface it is receiving
data, so you can send data through either interface without having to change the plotter
settings. (More on interfaces ' chapter 5, w Input/Output Interfaces.)
