RFC2217: write_timeout is currently not supported

[noud-github]

I found Issue after updating to 0.31.2.

on 0.21.40 this works like a charm:

serial_port:
  port_name: rfc2217://somewhere.lan:2217
  baudrate: 57600  # or 115200, YMMV

after the upgrade to 0.31.2
this end with write_timeout is currently not supported

I worked around this issue (for now) by using socat to create a virtual tty connected to the rcf2217 port, and mount that in the HA container,

Unfortunately, RFC2217 is not supported from version 0.30.0 (and 0.31.x).

This may change in the future, but current focus is on the new MQTT feature.

Thanx for sharing, switching to mqtt makes a lot of sence.
