Yes, at 9600 8N1.
Your /etc/ttys should state:
tty00   "/usr/libexec/getty std.9600"   unknown off secure
                                                ^^^ could be on, i'm not sure ;)
                                ^^^^that you can change for dif. speeds
modem port is tty00
printer port is tty01
(XON-XOFF flow control: that's only local for that other computer)
