New Program for Monitorng LPT ports

If anyone is interested I just finished my LPT_SPY.exe it is a DOS TSR
when loaded will
monitor the complete status of a printer port. I made it CNC oriented,
that is to say the display
is not in normal HEX, it displays each bit as a 0 or 1
Something like this
378 11001100
379 11001100
37A 11001100

where 378, 379, 37A are the port addresses and 11001100 are the data
bits, normal ordering
MSB---------LSB

I find this kind of display a lot easier to use when it comes to
debugging with a Voltmeter !

It will accept address
3BC
378
278

I wrote it in assembly and C++ , just tested it on my Pentium II and a
regular Pentium P5.

Full description at my web site. It is a tolerant TSR and unloads
gracefully.

Follow the link to the Download Page and at the button of it to the
LPT_SPY page...

Please let me know if there are any major bugs...

I tested it running CNCPro and MAXNC worked fine with both programs.
