rje has asked for the wisdom of the Perl Monks concerning the following question:

Here's a question, out of the blue, for the gearheads.

Can perl operate a port on my PC? Can it listen for
signals and respond to them? Can it talk on the printer

The thought just occurred to me that if it could, it would
be much easier for me personally to write a 'driver' for
a specialized application using the printer port,
than to write it in a language I don't have a compiler
for (C, for example).

My venerable Commodore 64 uses a really simple protocol
to talk to its disk drive; some have written drivers to
use the PC as a virtual disk drive for the Commodore.
Perhaps I can do that too, in perl...

Thanks for your time...
