Hypertherm XPR woes

Thanks for the input guys. I have been able to get quite a bit of the interface working, (display alarm/state, query status of all components, get firmware revisions, set source, set process, and fire torch), but there is still a healthy chunk more to test and work out.  Unfortunately, the XPR I have been connected to has to ship out in a few days and I just came down with the flu.  I have written a python script / hal component to upload and download sdos with a back door local network socket connection to do large multi-index updates and to set things from the gui.  It seems to be working adequately, but still needs a few tweaks and more testing to make sure it is robust.

TRUE HOLE

Hypertherm has a list of features a cnc has to be capable of in order to claim it can support 'True Hole'.  The biggest hurdle is that given an ending feedrate for an arc segment around a hole, it has to be able to ramp up velocity, (the feedrate), linearly from the beginning of the arc segment to the end of the arc segment.  I don't think we have that ability with linuxcnc.
