Chapter 9 Network Device Driver Options 137
netbiosretries
Specifies the number of times the NetBEUI driver retries
transmissions at the NetBIOS level before assuming that the receiver
is not present. This entry is specific to name claims, session setups,
and similar activities.
For another limit on transmission attempts, see the dlcretries entry in
this section.
netbiostimeout
Specifies the time in milliseconds that the NetBEUI driver waits
between retrying transmissions. See also the netbiosretries entry in
this section.
packets
Specifies the number of I-frame packet descriptors that the NetBEUI
driver can use to build DLC frames from NetBIOS messages.
A 63K message typically consumes 50 packets. Increase the value of
this entry for an OS/2 server that sends to multiple clients
simultaneously, especially when the data transferred is bulk data.
piggybackacks
Controls whether NetBEUI sends and requests data
acknowledgments “piggybacked” with incoming data. This entry
increases network performance by sending data and an
acknowledgment of received data in the same frame. A 1 means to
send and request piggybacked acknowledgments; a 0 means neither to
send nor to request them.
If piggybackacks=1 on your computer and the other computer
doesn’t support piggybacks, the other computer should ignore the
request and send a normal acknowledgment. You may want to set
piggybackacks=0 when the other computer may not be returning
sufficient packets to send piggybacks at a satisfactory rate.
pipeline
Specifies the number of NetBIOS message packets that are prebuilt
and waiting in a pipeline for each session. Increase this value if you
usually send long streams of packets. Decrease the value if you expect
to send short, occasional bursts of packets.
