units are accessed by selecting 

Next unit

by pressing the highlighted character (

to the main menu by pressing the 

<ESC>

<ESC> key. 

 
Once a server port is selected, the on-screen menu will disappear.  With the default 
settings, a small box with the port name will appear at the top of the screen when the 
on-screen menu disappears, and then disappear a few seconds later.  This box with the 
server port name may be configured to never appear, to appear for a few seconds, or to 
always remain on the screen; its position and colors may also be configured.  See 
section 3.7 for more information. 
 

At start-up, server port 1 is selected by user A, and user B is disabled.  User B actually 
has a special port selected: the "parking" port.  The parking port allows two users to 
exist on the system without requiring that a server port always be selected, freeing all 
server ports for possible selection when a user is not active. 
 
The parking port may be selected by choosing the Disabled item just above the first port 
in the port selection list on the main menu.  Both users may select this item 
simultaneously.  It is recommended that a user select this item when not active to 
prevent a server port from being blocked from the other user.
