Serial port problem when disabled in BIOS

[Necati Ersen Siseci]

Hello,

I am using FreeBSD 5.4-RELASE-p8.

When i disable the serial port ttyd0 and try to write to ttyd0 system get stuck.

For example, after disabling serial ports from BIOS and issuing

echo > /dev/ttyd0

or enabling ttyd0 on /etc/ttys will get stuck the system when booting
up and try to
run getty for ttyd0.

Sincerely,
