[GreenKeys] Model 35

[Larry Tighe]

Jim,

That analogy fits the situation.  Being a KSR, the only way to stop the 
sender would be as you say,  trigger a stop (to blind) on the KB.    There 
is a button to "Unblind Keyboard" to the right of the KB.

Now I have to trace wiring to see what it does in the ESU...a scrambled 
mystery  LOL.

Thanks to all for input.
