GPIO isr is not working

[DrMickeyLauer]

We're pretty much offtopic here, but why-oh-why is idf.py monitor not using CTRL-C (or CTRL-D) to exit instead of using this crude completely non-standard key combination? I'm almost ready to patch it...

Because Ctrl-C and Ctrl-D result in useful ascii characters (break and EOF, respectively) being sent over the serial line; there's bound to be some people for whom those are useful (e.g. when porting POSIX applications). Ctrl-T or Ctrl-[ generally doesn't result in anything immediately useful.
