I had a suspicion that was the case, but couldn't confirm it.

Then something more sinister is at work here. A 'cu -l /dev/ttyu0'
will "connect" me, however I get no prompt, and not input or output
seems to be passed to the console port. All input gets dumped to the
shell I executed the cu command from, *after* I kill the first (lowest
pid) cu process.
Example:
yang# ps -ax | grep ttyu
687 ?? I 0:00.01 /usr/libexec/getty std.9600 ttyu1
688 u0 Is+ 0:00.01 /usr/libexec/getty std.9600 ttyu0
741 p0 R+ 0:00.01 grep ttyu
yang# cu -l /dev/ttyu1 -s 9600
Connected
*hit enter a few times, type hello john, then kill the first cu
process from another shell*

yang# hello john
hello: Command not found.

Reading the handbook section on serial communications again, I don't
see anything wrong. I'll be the first to admit this type of stuff is
uncharted territory for me. If I skipped some required reading on the
subject, please don't hesitate to point me to it.
