Well i guess you could fix about everything by reading the actual motor position and tell him to go to the readed position.

well to make it more clear... here's a snip of the idea

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 
       ' SERIN motor position
       ' SEROUT motor position to make him stop
       endif
    
    goto MAIN
    End

it's an idea. Let us know!
