fyi, PC Engines sells the serial-usb adapter

[mdickers47]

Just in case you want to add to your writeup--as long as you are ordering from PC Engines, you can throw in a USB to serial adapter that is pre-wired null-modem style for $8. It works as a direct connection to the APU2 from Linux with no configuration or fooling around with drivers.
