Terminal messages arrive without target serial port #1129
Description
When keys are entered in the terminal, 'serial-terminal' type messages are sent to BPL without the target serial port. propterm.js calls blocklyc.js' getComPort() to form 'serial-terminal' messages to BPL, but it seems that getComPort() doesn't work in that context... always returning an empty string.
I don't know how to fix this. @MatzElectronics, can you assist?
