RE: [CAD_CAM_EDM_DRO] Re: Compters without printer port

Hey, Les:

I had that same problem with XP(I also had it when I tried Win2K) that the PC would not boot up if the parallel ports were plugged in to the breakout boards.

I was beginning to think I was crazy, as I reported it on the Mach forum, and nobody seemed to have ever heard or seen anything like it before.

Do you want to thing about that a bit more?
USB to Parallel converters are not suitable for 'creating' a parallel port even
for 'slow' signals which you just want to switch on and off. They are designed
to handle parallel printers and little else. Certainly no use as a replacement
for a driect parallel connection to the processor.

You need an add on card that picks up the parallel bus, such as a PCMCA card,
although even those can be a little 'slow'.

I've been playing with a couple of PCI buss cards to add extra parallel ports,
but I'm finding that XP can have trouble starting up with breakout boards
attached. No proble what so ever with W2k - so I've simply dropped back to that ;)
