Hi All
 
How do you use momentary (updown mode) in a .tx statement?

i cant seem to seperate the .tx values to correspond to on/off states
of the button, it just chucks out both the on and off state on the on and off (wow that must sound confusing :)

heres an example ;)

$button 41
  .showvalue on
  .mode updown
  .minmax 64 127
  .tx $B0 $0F $7F  (i want this to be the on state)
  .tx $B0 $0F $40  (Want this to be the off state)

hope that clarifies my ramplings ;
at the moment it chucks out both states on button and off

cheers
Anton
