Bandpass Filter Control

I've asked this question on what I thought was the NA Reflector but got no
answers. (Is there really an NA Reflector?) Perhaps some one can help. 

I have managed to get N6TR's software to control (via LPT) the Top Ten
Devices decoder switching a Dunestar BPF on the output of my Yaesu. The BCD
information is on pins
2,7,8 & 9.  All seems to work as expected. 

My question is about the use of NA to provide the BCD output to the Top Ten
Box. Do I simply use LPT pins 2,3,4 & 5 when running NA? Or is there more to
it?  No mention is made in either the Top Ten manual or the Dunestar manual.
I hope to get any answer before attempting to build yet another
cable/adapter. (Did anyone ever tally up the number of separate cables,
connectors, adapters, etc. that "computers" have added to the "radio station"
....and they call this wireless!)

Also, my Ver. 8 CT manual says nothing about controlling switches via LPT
port. Yet Top Ten says the feature appeared with Ver. CT Ver. 8.52
ought to do it. If so how do I enable the feature when use CT?

Any help would be appreciated. PLEASE direct relpies to me, NOT the
Reflector. Tnx!

Actually there is only a cw AND digital band!

Actually come down there and listen sometime. Check this weekend which 
oughta be kinda interesting. The JARTS contest is running on RTTY and the 
JA's go well below 7.025!  Don't QRM us just cut us some slack!

Actually some of us Digital Guys even copy! I think you are talking about 
packet and ... ...

They have! Its called the CW and digital band. No SSB is allowed. Only 
problem is cw is digital just most of you/us don't use a computer to 
decode it, why just the other Hal's dog brownie was copying this RTTY 
signal by ear....

Well I guess the problem will probably go away by shifting the finger 
pointing to someone else. Maybe the solution is to do away with cw and 
make the entire band SSB.

(just kidding :-)  ... heh heh)

Actually my prediction is no-code by 1998 and if the phone guys are 
worried now...whew....

But 40 meters is a problem. About time we spread down to 6800 or 
something as that appears to be the only solution. As to those doing SSB 
on 7.003 I don't think they are responding to anything. Kinda, like those 
who are on 20 meters doing 1200 baud packet with a complete network 
running VHF protocol packet in the middle of the digital band. Complete 
with frequency cop's and all.  Makes an Alpha 87 come in handy.

Credit this gem to N6AA:

Fi Ni is much easier to say than Five Nine and sounds the same over
the air.  Cuts down on fatique.

Have fun!!
