Linuxcnc real-time spindle/feed overrides alternation

Hi fellows,

I wanted to change the linuxcnc machining in real-time for its spindle and feed overrides, I was looking at the python scripts but our final goal is trying to send the G-Code while at the same time sets the spindle/feed overrides. 
I had previously read the python codes but for the axis example, is the code being sent as a command and and added into the queue, that's not desirable as it is not simultaneously executed.

Kind Regards,
Ken

Not shure if this is what you looking for

www.forum.linuxcnc.org/38-general-linuxc...tter-control?start=0

How about this?
linuxcnc.org/docs/stable/html/gui/halui.html#_feed_override

Of course you can do this with python code too.

Thank you guys, I will take a look into those forum codes and feed you back some ideas guys.
