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.

Auto Ring Speed Detection
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
“Changing Configuration Option
Settings
” in
Chapter 5
