[BC] Parallel Port Script Needed for EAS Activations

[Steve Lewis]

See http://www.codeproject.com/KB/dotnet/ezSprinkle.aspx for some
information on using the parallel port.  This guy goes into a little detail
of how the software can control a parallel port.  He ignores the issue of
inverting the parallel port lines with an inverter (he's using the port pins
to supply +5 to the LEDs.  He ought to buffer and connect the commons of the
LEDs to +5).  If you've got an old 95 or 98 windows machine it's easy to
implement.  2000 and beyond are a little more software work.

I do not think that a "script" will do it anymore. The operating system
prevents one from writing directly to ports. If someone writes some Windows
code, I suggest that they use a "COM" port, i.e., RS-232C and manipulate a
modem control lead like RTS or DTR. there is lots of sample code on the
"Net" that can be used.
