Duplexing. A performance option that lets you choose how 
the adapter sends and receives packets over the network.

   Half duplex. The adapter performs one operation at a 
   time (because send and receive lines are shared); it 
   either sends or receives.

   Full duplex. (Requires full-duplex switching hub.) The 
   adapter sends and receives packets simultaneously by 
   using a different wire to perform each function. This 
   feature can improve adapter performance by eliminating 
   collisions. 

   Warning:  Incorrectly forcing a specific duplex mode may 
   result in poor performance. Consult your LAN 
   administrator before forcing a duplex mode or if you 
   don't know what kind of hub you're attached to.


Configuring for full-duplex
===========================

If the link is full duplex, set up the connection type 
using the SET2400 utility on the CardAssistant diskette.

Note that performance may suffer if your hub is not full 
duplex and you configure the adapter to full duplex. Leave 
the adapter on half duplex if you are not sure what type of 
hub you are connected to.

1.  Boot the computer into DOS with no drivers loaded. (In 
    Windows 95, boot into the "Command prompt only" option. 
    Press the F8 key when the message "Starting Windows 95" 
    appears, and select "Command Prompt only", which is 
    Startup menu choice 6.)

2.  Insert the CardAssistant diskette in the floppy drive 
    and launch SET2400; type "A:\set2400".

3.  Use the arrow keys to select the card (if necessary). 
    Press ENTER. 

4.  Select Configuration. 

5.  Use Enter and the arrow keys to select connection.  

6.  Press F10 to preserve your change.
