You can still use that communication to chat with the person about the
meeting, where you can share you USB/CD/tape drives with terabytes of
NNCP packets :-)

>Taylor UUCP does still have half-duplex support in various protocols!

I used to use USRobotic Courier with its proprietary HST protocol that
was literally just amazing on bad channels, like nearly the whole
telephone system was in Russia in 90s :-). So those Couriers were some
kind of de-facto hardware to work with and it was worth of it! And here
I got to know that half/full-duplex meant :-). HST protocol was some
kind of half-duplex (it can reverse its "directions", but made it very
slowly) and you could not use bidirectional full-featured transmissions.
In theory NNCP can be used with it with explicit tx/rx directions, where
only small DONE-packets are sent back. Of course I doubt anyone checked
it in practice :-)

Just out of curiosity, do you have experience with Kermit protocol? I
read many articles saying that Kermit is better that UUCP's
protocol-g/whatever, others are saying otherwise. Just interesting. Wish
I had enough time to play with all that things :-(
