exit serial console on F4

[Roger Neth Jr]

Hello List, I am experimenting with serial consoles and had tty00 open on 
fvwm X windows term. Closed the term and went to ctl-alt-F4 and logged in 
root to cu -l tty00 and connected successfully.
I tried ^C and ^D to disconnect from the serial console without success. 
What I am trying to do is open tty00 back on the fvwm X windows term but 
ports are busy because tty00 is running on F4.
I did a quick FAQ and Google but did not find anything.
Thank you,

rogern
