Sheesh, I obviously didn't do enough research. For $200 you almost
get "telnet" to the Nova :-) Hard to argue with that!

It solves the physical layer problem -- for one simultaneous
connection -- no need to write SLIP or find an ethernet card.

Its ability to "dial out" to ip/port means writing simple user
clients is easy enough. Write FTP in FORTRAN4!

Incoming for one simultaneous connection is "good enough" for
moving data in/out, a hell of a lot better than zero.o

I'm printing out the manual. Thanks for the pointer to this great
device!

It's unclear if, for the trivial case (eg. connecting a computer's
serial console to) whether it can supply "session" status; eg. DTR
high upon connect, and DTR false on CLOSE or timeout.
