I believe the OP wants to use a FreeBSD machine, that has several
serial ports and a network connection, _as_ a terminal server.

I can think of no reason why such an arrangement could not be made
to work; the question is whether someone has already written the
necessary FreeBSD code to accept a telnet/ssh/whatever connection,
initiated by a Windows terminal-server driver, and _transparently_
connect the session to a serial port on the FreeBSD machine via
tip(1) or some such.  (If all that's needed is access from a Windows
Command window, it is a simple matter of ssh-ing to the FreeBSD box
and then running tip(1).)
