Recent discovery: forwarding serial ports over the network is pretty easy. Useful for embedded development!

For example, if you’re working with an ESP8266 SDK in a Linux VM, but the device is attached to a FreeBSD machine: run something like doas python2 ~/rfc2217_server.py -p 8266 /dev/cuaU0 on the host and use something like rfc2217://192.168.1.2:8266 as the --port argument to esptool.

(Yeah, use that script. Other RFC2217 implementations don’t seem to support binary mode for some reason.)

That feeling when something you’ve been looking for (but couldn’t find anywhere) just pops up on the GitHub dashboard. This time, FreeRTOS for ESP8266!
