The error message mentions /dev/ttyd0, which is a so-called call-in port. From
http://www.freebsd.org/doc/en_US.ISO...ok/serial.html
Quote:
In FreeBSD, you access each serial port through an entry in the /dev directory. There are two different kinds of entries:- Call-in ports are named /dev/ttydN where N is the port number, starting from zero. Generally, you use the call-in port for terminals. Call-in ports require that the serial line assert the data carrier detect (DCD) signal to work correctly.
- Call-out ports are named /dev/cuadN. You usually do not use the call-out port for terminals, just for modems. You may use the call-out port if the serial cable or the terminal does not support the carrier detect signal.
Note: Call-out ports are named /dev/cuaaN in FreeBSD 5.X and older.
If you have connected a terminal to the first serial port (COM1 in MS-DOS®), then you will use /dev/ttyd0 to refer to the terminal. If the terminal is on the second serial port (also known as COM2), use /dev/ttyd1, and so forth.

Can you try another cable? Does the same problem occur when you use another FreeBSD box as terminal (using
tip or
cu?
Or try to use
3wire.9600 instead of
std.9600 in the "/etc/ttys" file as recommended in the FreeBSD handbook (24.3.3 Troubleshooting Your Connection)
