Miscellaneous Questions on NetBIOS Compatibility

SUMMARY

The following are some miscellaneous questions about NetBIOS compatibility with various products:

1. Q. Is the NetBIOS implementation included in OS/2 LAN Manager version 2.00 (that is, NetBEUI) capable of full peer-to-peer operation?
   
   
   1. Yes, NetBEUI is IBM NetBIOS 3.0 compliant (some of our own extensions have also been added to OS/2 LAN Manager).
   
   
   



2. Q. Is NetBEUI compatible with the IBM Local Area Network Technical Reference SC30-3383-2?
   
   
   1. As stated above, NetBEUI is compatible with IBM NetBIOS 3.0. NetBEUI is compliant to the NetBIOS 2.0 specification, with the following noted exceptions:
      
      
      1. Trace (0x79) is not supported.
      
      
      
      2. Alert Ring (0xf3) is not supported.
      
      
      
      Microsoft has confirmed that these commands are missing. Support for these commands is being considered for inclusion in a future release as a part of the continuing convergence process of OS/2 LAN Manager and IBM LAN Server.
      
      Also, there is one NCB (Network Control Block), NCB.FIND.NAME (0x78), that is documented incorrectly in the NCB.H file as NCBRCVPKT. This command does return a buffer that complies to the IBM NetBIOS 2.0 specification for the NCB.FIND.NAME. The only difference from the specification is that the buffer described in the documentation is an 802.5 (Token Ring) link layer header rather than the 802.2 (Ethernet) link layer header of the frame that is actually received.
   
   
   



3. Q. Do the same answers to questions 1 and 2 also apply to UNIX LAN Manager/X?
   
   If the specific UNIX LAN Manager/X implementation adapted by a particular OEM supports a NetBIOS API, then yes, this information also applies to the OEM's implementation.
