You're not married, if you were, you would know what append when someone speek
and the other doesn't answer ;-)
a download have to be coordinated, exchange of info both way...

that is an interesting point here, this solution migth work better, concern is
amount of current that the transmitting circuit can give to the IR LED, bits
rate ( since it is serial, should be low enough (unless you use the USB)), how
the IR receiver circuit is design...
I think I should open one... where is that screwdriver
