Wherever I put this code (While (PortA & %00011100) = 20 : Wend) the result are always the same : full command is sending.

Recap :
- if I push button for VolUp (case 20) I need to send this code : Starting (heading) , followed by VolUp command (body). If the VolUp it still pressed, while the button is pressed, only body must be sending ;
- the next time I press VolUp, the whole process must be repeated : Starting, followed by body while buton is pressed ...

Maybe instead of (While (PortA & %00011100) = 20 : Wend) I must use another command ... but I dont realise which one ...
