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).)
