Is the serial port enabled (BIOS & kernel)?
Do you get positive output when you do
   $ cat /var/run/dmesg.boot | grep "sio[[:digit:]]"
  sio0 at port 0x3f8-0x3ff irq 4 flags 0x10 on isa0
  sio0: type 16550A
  sio1 at port 0x2f8-0x2ff irq 3 on isa0
  sio1: type 16550A

In /etc/ttys
   ttyd0 "/usr/libexec/getty std.9600"   dialup  off secure
means first serial port; cable is connected to that port?
