Most null modem cables only have three wires inside. FreeBSD wants more (specifically, it wants the CD line). Look at: http://www.freebsd.org/handbook/handbook137.html#330 for specifics (especially the section on cables). If you make (or get) a full null-modem cable, you should set the VT220 to hardware flow control (not XON/XOFF). If you want to use the (probably partial) cable you have, you may use cuaa instead of ttyd and XON/XOFF, but beware: some programs don't like this (pine for one will need special setup, and pico will not work at all).
