Assuming you are trying to set software flow control for
a typical login session, enter the command 
		$ stty -a 

and look for 'ixon'.  If it appears as 'ixon', DC3-DC1 flow control
is enabled (i.e., the host will act on receipt of these characters).
If it appears as '-ixon', it's disabled.
Likewise, to turn it on or off, enter "stty ixon" or "stty -ixon".

If you want to look at the flags for a port other than the one
you are logged onto, enter
		$ stty -a < /dev/tty_whatever

[I'll hold off on hardware (RTS-CTS) flow control since I probably
have already answered your question.]
