Parallel Port Preferences

Parallel port

The communications port that will be used by the parallel port test, eg /dev/lp0, /dev/lp1 or /dev/lp2 (only ports currently installed will be displayed). See the parallel port test for more details. See the parallel port test (Chapter 3, Parallel Port Test) for more details.

Only a single parallel port may be tested at one time.

Test type

It is possible t select either a “Detect and loopback test” or a “Detect only” test. The, detect and loopback test, requires the use of parallel port loopback plug (see Appendix D). The, detect only, test does not require a loopback plug. When possible use the loopback test as it is a more though test.
