Description Jan Alexander Steffens (heftig) 2016-11-01 20:48:59 UTC 
Provide a property for indicating (and manipulating?) terminal flow control status, i.e. XON/XOFF. This could be used by gnome-terminal to display a notification while the output has been suspended.

One possibility seems to be putting the pty into packet mode (see TIOCPKT in tty_ioctl(4)), which signals when the output is suspended or resumed.
Comment 1 Egmont Koblinger 2016-11-01 22:47:35 UTC 
This is half done. Packet mode is already enabled.

There's a proof of concept patch that changes the cursor's shape when output is suspended. It is yet to be cleaned up / finished, or maybe changed to a notification so that gnome-terminal (or any vte-based app) can display a symbol anywhere it wants to rather than vte changing the cursor shape.

FTR, I was thinking more of an app-notification like the widget factory has on its second page.

"like the widget factory has on its second page" -- sorry, I totally don't understand what you mean here.
Comment 4 Jan Alexander Steffens (heftig) 2016-11-02 08:13:31 UTC 
Open gtk3-widget-factory, go to page 2, then use the spin buttons on the top left to set the value to "51". A notification will appear.

Got it :)
