I dabble with electronics along with other tech and noticed that the Flint 2 has serial port terminals on the pcb (ref: [Openwrt / MT6000](https://openwrt.org/toh/gl.inet/gl-mt6000#serial)). My experience with Linux is limited, though I have built several Pi projects. I attempted to identify the internal serial port via a few CLI commands such as dmesg | grep tty, but haven't been able to verify the OS sees this port. Still, I have to believe it's possible somehow.

Has anyone experimented with this? I've got an idea to use [lcdproc](http://lcdproc.omnipotent.net/) for a small lcd display that could show cpu, traffic, lan port up/down, etc. I miss the blinkenlight leds.

TIA

I'd try these maybe. Also look for uart on board. Wonder how far the banana pi router is from this.

Thanks for the suggestion - I'll check that out!
