Well, some investigation, shows that the NETAPI.DLL is supported BOTH by
Novell and IBM (NetBIOS Submit), while the ACS library (netBIOS NB30) is
only supported by IBM.  So the compatibility issues are solved.

But I still have some questions regarding NetBIOS (the NetBIOS Submit/NETAPI
package).  It is possible to open the driver in three different modes 
(REGULAR, PRIVELIGED, EXCLUSIVE).  What I don't really understand, is
what I can do with the different modes.  What I want to do, is to receive
DATAGRAMS, and this seems impossible in REGULAR and PRIVELIGED mode?  WHen
I try to open the driver in EXCLUSIVE mode, it refuses with an ACCESS
ERROR.  Supposedly there is another application (the Lan Requester?) that
already has opened the driver in PRIV/REGULAR mode, in which case the
EXCLUSIVE mode can't be used.  But in that case, it would be pretty
hard to use the EXCLUSIVE mode for anything at all?

What I want to accomplish, is to get the same functionality by using the
Submit/NETAPI library, as I get by using the NB30/ACS library.  When I
use the NB30 interface, I seem to have complete control of the NetBIOS
session (I can RESET and receive DATAGRAMS).

I have also noticed that the Submit/NETAPI DLL don't automaticly de-allocate
the resources I have allocated, when issuing the NetBiosClose call.  I
have to manually delete all names that I have added, before closing the
device.  If I don't I seem to loose all control of that name, as I can't
add the name again (already in name table, naturally) and I can't delete
it at that time, as I have lost the referencing num-fields.  I thought the
NetBiosClose call was intended to ensure that all resources I claimed, was
released.
