Re: [CAD_CAM_EDM_DRO] DeskNC Windows version

Hi Art,

Thanks for the reply. I'd heard that parallel was impossible, and
serial possible under windows. Is there any EPP/ECP support under
windows? Might that work better, similar to serial? But then, it
wouldn't be a "simple" parallel port, I guess!

By 8000 PPS, are assuming a 133Mhz Pentium class machine on Windoz? I
thought I'd heard higher numbers, must be for Linux or DOS.

I'd also like to hear about the P6 instruction(s) that aid in
timing/step generation.
