Joe,
Either approach should work. Here at K8CC, we use the second approach you
mention - that is, put three COM ports in one computer and feed the ASCII
spot data to that computer as if it was a TNC.
Both approaches require at least one computer to have three COM ports.
However, using the first approach you mention if the Windows computer
crashes for any reason the NA network is interrupted and QSOs are no longer
passed. This can be dealt with by merging the logs after the contest is
over, however if you isolate the NA network to just the logging computers
one failure mode is eliminated. Our experience has been that the current
version of WinTelNetX program runs pretty much trouble-free, although you
have to occasionally check the connection to see if the Internet cluster
has dumped you.

Subject: [na-user] NA network
I'm working on a six station NA network that will be fed packet data. I
am using K1TTT routing program. Got that figured out. Should I feed
the data to one of the logging stations direct or should I feed it back
into the computer pulling the packet data and include it in the NA
network?
That is should I run NA on the packet data acquisition computer
pump the packet data out com1 back into com2, then setup a com3 to connect
to the NA serial network? (com1=k1ttt port, com2=tnc, com3=na network)
Or just put 3 com ports into one of the logging machines and feed it the
packet data? (com1=radio interface, com2=na network, com3=TNC port,
lpt1=cw interface)
