Re: [CAD_CAM_EDM_DRO] Windows CNC Software

Jon,

What do you know about the Parallel an Serial ports on the PCI I/O
cards? I had written directly to the old DOS port addresses, but a new
system (all PCI slots) put the a new card's Serial ports at COM 5 & 6,
and I have no idea where the addresses are. Same for the Parallel.
Makes it hard to do CNC on a new machine. Windoz98 doesn't help much,
either.

We should be able to access ports (normal ones, anyway) through a DOS
window on Windoz98.
