In addition to the Lua reserved words, you also cannot use command group names as variable
names. Doing so will result in the loss of use of the command group. For example, if you send the
command digio = 5, you cannot access the digio.* ICL commands until you cycle the power to the
instrument. These groups include:
beeper
bit
channel
digio
display
eventlog
errorqueue
