reuse of unused RX pins

[lokki]

hi there,

i need several MIDI outputs for a controller (4 for a start) but no inputs. since i am a bit low on digital pins, can i reuse the RX pins of the respective Serial lines for other things? simply declare them as OUTPUT? do i need to do anything special in the midi library to turn them "off"? (so the buffer is not filled up with garbage for example) or is this not possible?

pinMode() after Serial#.begin() will reconfigure the pin - not sure if it will disassociate the Serial hardware fully?

Try:
Serial1.end();
Serial2.end();
Serial3.end();
then
pinMode(Pin, OUTPUT);
