RFC2217 Remote Serial connection fails

[gernoteger]

When starting esptool over a RFC2217 remote connection it fails.

This commit introduced write timeout which isn't implemented in rfc2217.py

Full output from esptool.py (please copy and paste all lines of output)

Do you have any other information from investigating this?

This seems to be starting with commit 47302cf first visible in version 2.5.0.

Workaround: Revert to 2.4.1

How we can revert to 2.4.1

Clone repo locally and check out the corresponding tag. You'll see it in git log.

Ran into the same issue here using the esp32-idf, I guess I can do something with git modules to change the version there?
