Jon,
 

I learned from the SX-4 code and the NV article to correctly interface the SX-Key Help (SX-28 keyboard example) to my BS2px. 

 

It works great using Open Baud "True" 9600. 

 

I went from using 10 BS2px pins for individual pushbuttons to 1 BS2px pin as a serial input for the SX28 matrix Keypad driver circuit. 

 

When my matrix keypad comes in next week, I will be able to truely test it (other than using some wires and resistors for the time being).

 

You are a wealth of knowlege and resources.

 

Thanks so much!
