Here are list of the ADMIN commands from the Python v1.6 code:

Code:
Available ADMIN commands: DATE, TIME, KEYBOARD, NETWORK, TOUCHSCREEN, HALMETER, HALSCOPE, HALCMD
It looks like the only commands that take arguments are:
Code:
  • ADMIN HALCMD [pin] [sig] [param] (looks to be optional from the command parser)
  • ADMIN HALMETER [pin] [sig] [param] (looks to be optional from the command parser)
There is also another "unadvertised" (in the error message) command I would be comfortable sharing with the community. Please be advised this was not acknowledged by Tormach, so it may void your warranty or turn your machine into a autonomous killing robot =)

Code:
ADMIN BUGREPORT - Open Firefox and direct to https://bitbucket.org (you can browse away)
Hopefully this is helpful!
