Any computer owner/enthusiast
who likes to experiment should
really have an interface tester.
This need not be an expensive,
proprietary instrument: in most

shown in here is perfectly adequate.
The circuit may be used for
testing the level on serial interface
lines (COM) as well as on parallel
ones (LPT).
