To prevent this problem, the driver uses a ratio value 
to periodically send out a low-priority packet (if one is 
waiting to be sent).

For example, if a value of 1000 is entered, one 
low-priority packet would be sent for every 1000 
high-priority packets. A value of 25 is recommended 
for most applications.

An alternative way to access DynamicAccess Class 
of Service is to click the Properties button with the 
3C319 NIC selected while you are viewing the adapters 
list. Using this method also allows you to disable or 
enable the auto ring speed detection option.

The auto ring speed detection option permits the NDIS 4 
driver for Windows 95 and Windows NT to detect and 
operate at the current ring data rate. Auto ring speed 
detection is automatically enabled when you load the 
NDIS 4 driver. (This feature is not available with other 
3C319 NIC drivers.) 

To manually set the ring speed after disabling auto ring 
speed detection, see
