In recent tests, I connect to a running LinuxCNC 2.5.3 process (Axis 2.5.3 gui) 
with linuxcncrsh and nc. If I open an ngc file using linuxcncrsh commands like:
...
set mode auto
set open file.ngc
...
then the running Axis process shows that a new file has been loaded by a change 
in its banner, but the tool path plot does not update, nor does the displayed 
g-code. 

If you then Run the gcode in Axis, the path (corresponding to the new file) 
will be drawn superimposed on the previous file's plot. The Axis code display 
toggles ahead through the previous code while the live plot is doing something 
different. So its a mess. Axis is somewhat aware of the new open file, but is 
not initializing as it does, when a file is loaded using its own File Open 
button. 

This is no big deal, but I guess I am posting this in case the highly paid Axis 
team are sitting around drinking coffee and wondering what to work on next. 

Why you ask, well I am testing having Mathematica talk to linuxcncrsh - with 
Axis running on the remote operator workstation, and Mathematica acting as some 
sort of supreme being (generating the GCode and watching the build, but leaving 
the real time stuff to LinuxCNC). Retired people have far too much time on 
their hands...

PS: three of my posts to the list have vanished without a trace in the last 
week, so am crossing my fingers that this gets through.
