I'm trying to write Serial Data to COM x on Windows ( not using Linux at this time ). I'm using Hairless MIDI to pull data ( debug ) but not getting data. I can see ' Arduino Output Monitor COM(3) ' <-- simliar in Hairless when trying to pull data ( or listening ) but nothing. Tried sendNoteOn and Serial.write / Serial. print -- * Is there anyway to open a COM Port with Number to write serial MIDI data or any data too in Windows ? Thanks in advance !
