Adding consdev=com0 to boot.cfg normally causes boot messages and getty to show on the serial port.

When vesabios is configured in the kernel the kernel messages end as soon as the vesabios is initialized and no getty is listening on the serial port.
enable vesabios in the kernel:

# VESA framebuffer console
options         KVM86                   # required for vesabios
vesabios*       at vesabiosbus?
vesafb*         at vesabios?
options         VESAFB_WIDTH=1024
options         VESAFB_HEIGHT=768
options         VESAFB_DEPTH=8
#options        VESAFB_PM               # power management support
wsdisplay*      at vesafb? console ?
