Can you turn off buffered serial output for port 0 and try again?

I cannot really do any more troubleshooting right now, as my Arduino Uno is currently installed in my Magnum, doing duty as a transmission computer. I will have to order a few Unos from Amazon and wait for them to get here. Sorry about that.

That's.... weird. I had a bit of frustration, too, trying to get debug serial output working back in December, but I can't remember exactly what I ended up doing to get it to work. I think I sent an introduction string as the very first transmitted string.

There's not really a flag, as such. The code checks for the presence of a signature word in EEPROM, when it first starts after power-on. If the signature word does not exist (like if you reprogram with a ICSP programmer, and the ICSP programmer also helpfully erases your EEPROM for you, for instance), then the code writes a set of default stored parameters, then tells itself to start off with the settings screen.

I will tell you how to disable the going to the setting screen, but I will not incorporate it into the code. Go to about line 11831, and change this line from this:

	if (loadParams() != 1) doGoSettingsEdit(); // go through the initialization screen

to this:

	loadParams();

It will preserve the EEPROM signature checking, but will not force you to go to the settings screen if you happen to power up with a blank EEPROM.
