I use tip com1 to go out serial to serial of other server's redirected console. Just check /etc/remote and make sure you have a line as follows: sio0|com1:dv=/dev/cuaa0:br#9600:pa=none: But if you do serious console redirection, get a decent Terminal Server to which you ssh to the Terminal Server and then use its own commands to connect to your serial console(s).
