OK, I've found some sample code in C# for writing bytes out to the
parallel port, which should do just fine.

So, I'd like to suggest a new app:
"xPL I/O".

This will be a Windows service that will be able to write bytes out to
the parallel port (and maybe also other ports over time, hence the
reason for the generic name).

Bytes would be written using an xpl-cmnd message like:

Control.basic
{
Device=888 (decimal address of LPT1)
Type=byte
Current=255
}

In the above example, we are sending 255 to LPT1 (i.e. make all data
lines high).

Let me know if this is the sort of thing you're after and I'll get it
done.

Regards,

John
