Can't specify different upload and monitor serial ports.

[paulwrath1223]

The Sparkfun Pro Micro (and presumably the other 32u4 boards) use a different COM port depending on if it's in bootloader mode.
I'm currently trying to just get a blink sketch working on a Pro Micro, but cant get it working. I am totally liable to be making a giant blunder, but I can only upload by specifying the COM port, and then the program immediately crashes after uploading with an unspecified error.

Tested on Arduino Uno [edit: with a new project] and without changing anything it works flawlessly.

According https://store.arduino.cc/en-nl/products/arduino-uno-rev3 has an Arduino Uno an ATmega328p. And that is not a 32u4. Groeten Geert Stappers -- Silence is hard to parse

I should have been more specific, I have 2 boards.

When creating a project for the Uno, everything works fine (except the 'issue' described here: #248)

However, for the Pro Micro, I need to specify a COM port for it to upload successfully, and the serial output port is different.

Yeah, I'm aware of this shortcoming in the current design. I agree that it should be possible to specify an alternative port for the console and essentially disconnect the console logic from the flashing logic a lot more.

Let's take care of this after #522 is merged.
