Going the other way would suit me just as well.

An open on /dev/stream0/tserver.foo.com/2005 would
set up a connection to tserver.foo.com on port 2005
which the listener on the terminal server could map
to a serial port.  If done right this device could live in
places like /etc/ttys or /etc/ppp/ppp.conf

Baud/Parity etc setting might be a bit much of an ask though.
We would really need something like LAT instead of
just socket/stream/telnet like behaviour.  Terminal servers
are pretty good at sorting port stuff out in any case.
