Xon, Xoff (software flow control) mode or DTR/DSR mode (hardware flow control). 
In proton using Hardware USART command:
hserout [20] ‘XOFF…STOP TALKING
hserout [17] 'Xon

Using software command in Proton
Rsout 20 'Xoff
Rsout 17 'Xon

I got the numbers from http://www.asciitable.com/

It should be enough info for you to get started.

I never used flow control but it does require 3 wires in / out and flow control wire.  For more info on Serout just open Proton manual page 360.  Flow control uses Fpin.

SerOut PORTA.0/PORTA.1, 84, [17]
porta.0 is serout pin
porta.1 is flow control pin
84 is 9600 baud / 8 bit true
17 is Xon
