stdout read error

[nitimohi]

i ma getting the error:
File "", line 1, in
File "/usr/local/lib/python3.9/dist-packages/pppd.py", line 82, in init
self.output += self.proc.stdout.read()
TypeError: can't concat NoneType to bytes

i started chat-script with -e option so the process starts returning stdout ass soon as the process is started, not i still get this error as my process return anything on stdout after at least 1 sec.
is it batter to give some delay before read or or check the type of return ?

Latest code in repo don't have this issue, nut pip didn't pull the latest code

Same issue on an RPI4.

The issue occurred in a pip installed python-pppd. I pulled latest master and that version works for me.

Yeah, I realized the pip release and source are not inline and I've been meaning to fix that, I'm gonna do a new release in the morning.
