Are you sure you actually have to send the command three times? Personally I have NO knowlage about these things but I would've guessed (if this is captured from a remote for example) that it just kept repeating the command and postamble untill the button was released and then issued the 'FinalAmble'. So perhaps Preamble, Command, FinalAmble is all you actually need? Oh well, like I said, I have no idea really - just guessing, you'll figure it out.
