Some note on testsm (test smart motor program).

1. starting testsm with IO.

   ssh smokey2 -l smokey2
	cd current/mt
	testsm -m 6                  ; runs testsm using vfocus motor, do 'testsm -h' for help
	Enter Command: io            ; The io command - put you in a prompt that talks to the motor

2. vfocus notes - some example command to move the vfocus stage.
   vfocus goes from -100970 to  100970. Motor is connect to smokey_digi, port 2006
	On the GUI, vfocus is position are define as -1.0 to 1.0 (for -100,000 to +100,000 steps)

   initialize motor:
	   X A20 V40000  AMPS250

   move to positive limit
	   X A20 V40000  AMPS250 MV G        

   Query left limit (should be '1' after hitting limit)
	   RBl

   O set the step position. (Vfocus positive stop is 100970)
	   O100970
 
   Example of other useful commands for moving the motor:

	   MP P30000 G           ; move to absolute position 30000 (vfocus of 0.3)
		RP

3. Initializing vfocus from the GUI is the same are doing 'focus_init' in current/mt/
   You can also run 'vfocus_init -v ' for verbose output.
