Just tried everything again, from start to finish, for COM1, COM3 and COM5, with baud rate of 9600 and 115200 (so six complete attempts with those settings at the Windows level, Arduino IDE level and Repetier/Pronterface/Matter Control level). I've been changing the device name each time as well to make verify that the Arduino IDE write is working, and it's not failing at all. So far device names have included "My anus is" and "Something is" in an attempt to maintain humour.
But alas, no luck.
vreihen, I did try your suggestions, but I'm just getting no feedback at all from the serial monitor.
