RE: [CAD_CAM_EDM_DRO] Re: Interface. Gauging interest.

Jan,

There are drivers to make USB look like serial, but I haven't heard of one
for making them look like a parallel. Are they out there?

At any rate, the timing of the signals we want to put on the parallel pins
would no doubt be considerably distorted, and probably make the driver
unsuitable for our use. I'd like to be proven wrong!

I suggest that the USB "dongle" needs to be a little smarter. I'd like to
see something like the DeskCNC module with an FTDI USB chip, or implemented
in an 18F4550 PIC. And the protocol specs for the DeskCNC module made
public so that it could be standardized on (or is it already?).

No, we'd be away from the simplistic LPT interface we've been using, but
it's probably necessary if we want USB.
