>Description:
When rsh is invoked, it changes the tty state, and does not
restore the original values on exit.
>How-To-Repeat:
"stty -ixon"
"rsh <host>" (successful or failed login, it makes no difference,
to the local machine for example).
"stty -a" and observe that ixon is now enabled.
Example session:
stealth : ~ > stty -a
speed 9600 baud; 47 rows; 80 columns;

>Fix:
Unknown. Currently I have to reset the tty state manually
(stty -ixon, etc.)
