JNOS<>Mailtraq does that too, but you aren't tied to using them.

As usual, Hank is discussing in circles again. First he wants examples of
how TCP/IP applications can be used with packet radio, and once you give
them he starts talking oldfashioned packet radio protocols again!
Who would ever want this translation in the client software?
In a TCP/IP network, the clients are talking to corresponding services
on the network and server systems. Your BBS will be running INN and
sendmail (plus probably a POP3/IMAP server), no hamradio BBS stuff.
When there has to be any gatewaying, it will be done by the BBS system,
not the user software. Of course.
>Have you looked at SNOS to see what is needed?
I have never had a DOS-based system at home. Sorry.
My system is now running Linux, and I have NET running for the conversions.
I have not seen the need for anything different yet.

As others have noted, for the Internet market boxes like this are available
in many forms. And the software that would be needed in a TNC like this is
mostly available for free.
Integration to a product that can be sold may cost some money, and of
course it is easier to keep your customers dumb and not let them taste any
networking, or they will become hooked.
This worked well when the alternative was telephone BBSes, essentially the
same stuff as the packet radio system.
Too bad they then got the Internet, and saw the light. That meant the end
of telephone BBSes, and ultimately the end of packet radio as well.
That will be very expensive for them as well.

In the case of TFTP, it might be that TCP hadn't been fully invented yet
when TFTP was specified, but I'm too lazy to look it up.
The reasoning behind NFS was that the overhead of TCP connections would
needlessly impact performance, so NFS ran on top of UDP with a homegrown
reliable protocol that wasn't very sophisticated. With V3 came NFS/TCP,
which is indeed much better. Keep in mind NFS is also stateless, so a
stateless transport like UDP perhaps seemed to more sense early on.

Subject: Windows software for an SCS PTC-IIe TNC
NcWinPTC is free, and works very well with the SCS PTC-II and IIe.
Another super Windows based program for the PTCII/IIe is XPWin. There
is a fully-functional demo version available for download. Links for
both programs are on the SCS Website. I have used both programs and
both are excellent.
