Question:
When using the LAN Manager version 1.01 NetBIOS, we periodically
receive a NetBIOS return code 09 when sending a MSG.SEND.DATAGRAM
(A0). A code 09 is not a legitimate return code according to the IBM
technical reference Token-Ring Network PC adapter manual. What should
we do when this occurs?
Response:
This error comes from NetBEUI as it runs out of resources. You should
to increase the following parameters in PROTOCOL.INI in the [netbeui]
section, as follows:
1. If you are using the Mnetb/Mdlc stack (for more information, see
the "Microsoft LAN Manager 1.0 Network Device Drivers Guide")
Min Max Default
--- ---- -------
tx.u.buffers 2 32 4 + 1/4(commands=)
where:
commands 1 255 32
Tx.u.buffers controls the number of buffers allocated for the UI
frame including datagrams, status queries, and session
establishment frames.
2. If you are using the NetBEUI stack (for more information, see the
documentation enclosed with the release notes dated August 23,
1989):
Min Max Default
--- ---- -------
datagrampackets 2 1000 2 packets
looppackets 1 1000 1 packets
Datagrampackets controls the number of data descriptors to allocate
for packetizing NetBIOS datagrams into UI frames.
Looppackets controls the number of packets looped back on the
workstation. This parameter will affect the workstation issuing
MSG.SEND.DATAGRAM if it has also put out
RECEIVE.BROADCAST.DATAGRAM. It will receive its own datagram
through the loop back in NetBEUI.
