Problem with flow control in screen

Problem with flow control in screen

[Scott RoLanD]

I have installed the GNU program screen and set it to use "^q" as it's
escape character, and disabled its flowcontrol with the following
options in my .screenrc:
	defescape ^Qq
	defflow off

My problem comes when I try to use the magic key "^Q" to talk to
screen. If I am looking at a zsh prompt, it won't work, the "^Q" is
apparently eaten and never shown to screen. However if I am running
any other text program (like mutt, less, etc.) then the "^Q" works and 
lets me talk to screen. I have tried this with the zsh-option
no_flow_control set and unset, it doesn't seem to have any effect.

What is happening?

Thanks.

Hmm.

Those options are supposedly "useful multiuser sessions only" [sic]  
to change "the default command characters of users that will be added
later."

You should be using
	escape ^Qq
	flow off

I have no idea why running mutt, less, etc. would make any difference,
unless maybe they're aliases that use screen to create new windows.

It may or may not matter, but hearing 'mutt' and 'less' in the same
sentence reminds me they both support S-Lang.

Just worked for me (3.0.6-pre-3):
% screen -e '^Qq' zsh -f
% setopt noflowcontrol
(then do   CTRL-Q ?   and get help screen)

Guess we need more information about your system, zsh version, etc.
