More Tkemc stuff

[Ethan Vos <ethan-at-forward.ca>]

Last week I posted a note saying that I had trouble with my X,Z and A axis 
and how the Tkemc was reacting to them. The problem turned out to be that I 
am using 3 axes with the third as A while Tkemc is assuming that if there 
is an A axis, it's the 4th. Change the Z to a 1 and the A to a 2 and away 
we go.

Questions:

1. How can I get the estop button to be red when the estop is on? I tried a 
million things but could not get it to work. All I succeeded in doing was 
getting it red all the time.

2. Could someone please send me a quick .tcl that will write a number to 
variable # 1000? I just can't seem to get it.

Thanks.
