So, I did learn that the serial output displays the details of the boot process rather that just responding to command strings which was my initial thought but despite a lot of time and configuration I can't get intelligible output to my PC. It's just like you Acid Andy struggled with per your post I found elsewhere on the subject. I don't have another electronic device to connect to that I can think of and can't find a solution to invert the signal that is in my recreational league. I've written serial interface code to interact with measuring instruments but I don't see an application here besides, I read two post where the Pinephone was connected to a PC and I've tried it with direct serial cable and several usb to serial adapters and still only a ton of garbage characters to read.
I've re-re-flashed the latest image to an sdhc card, verified fstab and mmcblk0p1 and when trying to boot, it almost immediately falls back to the emmc installation with Maemo-Leste.
It's interesting that the LED now starts out green rather that red and also when trying to adjust the baud rate the setserial function has no effect and constantly shows the baud rate at 1500000 but stty will show the baud rate at whatever I set it to using stty.
My only thought is that my usb to serial converters are too old and don't support the baud rate and maybe newer ones might have a signal inverter function.
