ADMIN HALMETER works out of the box. (It is hidden from the default list in ADMIN)
Halshow requires you to place halshow.tcl in ~/tmc/tcl/bin and edit ~/tmc/bin/halshow to point to it. Once you have done that then ADMIN HALSHOW will pop it up for you.
You can use the halshow.tcl from any linuxcnc distro.
