On a few occasions our PICMaster failed different tests in the
'Verify PICMaster' option. I noticed that you have to turn *everything*
off to get it out of that undocumented mode. Due to the interesting
PC interface design, you can actually keep your PC alive if you switch
it off with Mr PICMaster switched on (on its own power supply).

Bottom line : Switch *everything* off, go and make yourself coffee,
drink
it and have a good chat before switching it back on.
