You probably need to tell the kernel to use the serial console: # echo '-h' /boot.config Ah, thanks. I don't have a /boot.config yet. Are you sure this file goes in the top-root directory?

I do have a file /boot/loader.conf. How about having in here the line console=comconsole (to divert it from the default: console=vidconsole) ? Or will that not do the same? Having -h in /boot.config will also allow the boot blocks to output to your serial console. I suspect console=comconsole would help the loader + kernel. It certainly couldn't hurt I guess :) If I understand the process correctly, settings in /boot/loader.conf override settings in /boot.config as the boot loader happens after the boot blocks. Thus by setting comconsole will negate any settings in /boot.config. Setting in both places is redundant and may cause problems for you when troubleshooting. For my serial console, I set my kernel flag to 0x10 so I have console options without recompiling. Then I do my serial console settings in /boot.config as it happens earlier in the boot stage and thus, I get my serial console a little sooner.

When I #cu -l /dev/cuaao/ I see the boot process, but it gets to the date prompt but doesn't show the login: i did install ssh, but won't let me login with the password I set for root. Any other methods for connecting? This system is connected in my local network, with a firewall protecting my systems. - i am not running xserver on this system Of course you cannot login as root over the ssh connection; that's a default behaviour for security reasons. Haven't you installed a regular user on this PC, which is also member of the wheel group to allow using su for becoming root? Funny, that I'm struggling with opposite problem: I do not get the boot messages over the serial cable, but do get the login prompt, which I do not understand :(. For the login prompt, I have following in /etc/ttys on the headless PC: ttyd0 /usr/libexec/getty std.9600 unknown on secure but be sure the serial port is enabled in the BIOS, and you have serial port support compiled into your kernel. Your cu command should then work, I suppose.

You probably need to tell the kernel to use the serial console: # echo '-h' /boot.config Also make sure you have the appropriate flags for your serial device driver, for sio on RELENG_4 use device sio0 at isa? port IO_COM1 flags 0x10 irq 4 or if you're on 5.x edit /boot/device.hints and set hint.sio.0.flags=0x10 (this should be the default though). There's another knob for uart(4) on 5.x but I don't remember it right now. HTH, --Stijn -- The very powerful and the very stupid have one thing in common.
