Reading if Pin is High or Low?

[mister_e]

Well i this could be as easy as..

MAIN:
    IF (UP = 0) AND (DOWN=1) THEN
       serout FM, T9600 ,["W01 01 200", CR, LF] 'Write velocity limit value 
       serout FM,T9600,["P01 270000", CR, LF] 'Send MOVETO_ABSOLUTE command
       ENDIF

    IF (DOWN = 0) AND (UP = 1) THEN
       serout FM, T9600 ,["W01 01 200", CR, LF] 'Write velocity limit value 
       serout FM,T9600,["P01 0", CR, LF] 'Send MOVETO_ABSOLUTE command
       ENDIF

    if (DOWN = 1) AND (UP = 1) then ' <=== Switch is in central POS
       LOW Break_Pin
       endif
    
    goto MAIN
    End

Just connect a PIC i/o directly to the controller BREAK pin... this have to work... i guess.

or if you feel to add extra parts...
