Has ANYONE any idea about how to use ISDNpm's "paketfilter"?

Having recently switched the home LAN from using both NETBEUI and TCP/IP
together to putting NETBIOS over TCP/IP, I'm now plagued with the "I'm a
poor little Windows machine: surely there's someone out there that would
like to talk to me" broadcasts on ports 137--139. I use ISDNpm under
OS/2 Warp to perform dial-on-demand for /real/ traffic. and have had to
suppress this, otherwise I'd have one of those apocryphal GBP3000/qtr
phone bills!
ISDNpm would appear to have the facility to filter out this traffic:
however, the documentation is exceedingly opaque (as it freely admits)
and I have no idea how to tackle the job.
Attempts to contact the author have met with a stony silence: can anyone
confirm her address, please?

I don't want the NICs running promiscuously with multiple protocols.
Update since last week's posting:
I tried ensuring that all Win9x machines on the LAN had a valid LMHOSTS
file; I even discovered how to place a relevant entry for the *domain*
into that file. Even with "nbtstat -c" showing valid NetBios names and
services for all the machines on the lan, and for the domain itself, they
were *still* attempting to contact my ISP's nameserver (as set in each
machine's TCP/IP Properties)
Still no one has given me any updated address for Willibald Meyer :-(
I've fixed the problem: this OS/2 machine is now running BIND v8.1.2a,
with a forwarders option to use my ISP's name server for anything other
than the local LAN. Since that time (about 18:00 today:-), there have
been NO spurious requests for ISDNpm to connect to Demon (the resolvers
of each machine, OS/2 and Win9x, have been told to use this machine alone
for DNS). I presume that whatever it is that the Win9x machines were
requesting every 900 seconds is now provided to them by my named.

Does it really matter that it doesn't provide the requested
response though ?

All the same, it's true. Until I started running named on the OS/2
machine, the ISDNpm trace window used to show an attempt to connect to
Demon's nameserver (which each of the Windows machines knew about) every
15 minutes (more frequently if there was more than one of the Win boxes
alive).
Since I've had named running, it's been perfectly quiet: not a single
spurious dial-on-demand. :-)
I suspect that the traffic may be requests for the apocryphal top-level
domain WORKGROUP (although in my case, I have changed from the default).
YOY does a Windoze box ask the *DNS* for this???
