This is going to be a long shot...but does anyone know if it would be possible to talk to your controller/breakout box's parallel port via an ethernet connected print server?
Here's an example of a tiny print server I use on my home laser printer, so every computer (including wireless) can use this printer, anytime:
Netgear PS101
Say I'm using Mach2...I bet it needs a physical print port to open and write to in teletype mode, right? So, there is no way this idea would work...
Just thought it might be neat to have a network or wireless connection to a CNC machine -- with no dedicated PC at the machine itself. Maybe if not using a print server, then some other type of interface (?)
