3.1 Initializing a Parallel Port
Using a parallel port is simpler than using a serial port since data goes in only one direction. GEOS does not currently support reading data from a parallel port.
Parallel ports are used primarily for printing, which is handled by the Spool Object Library. The information in this section is useful only to programmers whose applications will need to send data out through the parallel port without using the spooler. Most applications, however, will use the spooler for any and all parallel port use.
