============================================================
------------------------------------------------------------
Half duplex:

The adapter can only transmit or only receive packets at any
given time. It cannot transmit and receive at the same time. 
This is how traditional Ethernet works.   
------------------------------------------------------------
Full duplex:

The adapter can send and receive packets simultaneously. This
feature can improve adapter performance by eliminating
collisions. 
------------------------------------------------------------
WARNING:

The card and the connected device must be set to the same 
duplex mode. 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 the capabilies
of the attached device.
------------------------------------------------------------
Speed:

The AT-2700TX adapter card operates at a link speed of 100/10 Mbps.
The AT-2700FX adapter card operates at a link speed of 100 Mbps.
The AT-2450F  adapter card operates at a link speed of 10 Mbps.
------------------------------------------------------------
Autonegotiation:

Autonegotiation is not supported in Fiber (FX/FL) network segments.

NWAY:

Another term for autonegotiation. Trademark of National
Semiconductor Corporation.

NWAY is not supported in Fiber network segments.
----------------------------------------------------------------              
Manually configuring duplex and speed:

If the link is full duplex, manually set up the connection type
using the SETUP utility on the CardAssistant diskette or with
the NIC's advance properties on Windows 9X/2000. 
-----------------------------------------------------------------
Note:

Performance may suffer if the link partner is not 
full duplex and you configure the adapter to full duplex. 
Leave the adapter on half duplex if you are not sure.
-----------------------------------------------------------------
Using SETUP utility to change settings:

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 SETUP27 (AT-2700) or SETUP24 (AT-2400).

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.
