Jon Brase on the PiDP-11 list solved the problem for me. For future reference, you need to dedicate a tty line/host TCP port to the UUCP line, and tell simh to use it notelnet.

e.g.:

set dz en
set dz lines=16
att -m dz 1107
# UUCP needs 8 bits
set dz 8b
att dz -am line=4,1729;notelnet

And then on the Taylor UUCP side, point the UUCP port at localhost:1729 (rather than 1107).

Yup, and the output is exactly what I would expect:

# ./uuname
Format
16bitpi
# ./uuname -l
v7

That is, locally I am v7, and the only remote host I know about is 16bitpi.

v7 UUCP has no uuname command: I get uucp, uux, uuxqt, uucico, uulog, and uuclean.
Yep - that was BSDism, the version 3BSD -- uuname.c should just recompile and manpage is very google-able.
