I've two Tyan S1837-UANG boards which work very well with serial console at 57600 and minicom on the other end. I've set CONSPEED=57600 option for kernel config, built and installed /usr/src/sys/boot with /etc/make.conf including BOOT_COMCONSOLE_SPEED=57600. I think the latter is necessary for getting bootstrap to know the initial speed, otherwise it defaults to 9600. Finally set '-h' in /boot.config, disabled getty's on ttyv's and enabled getty on ttyd0. I'm using minicom -o on the other end. But you're running 3.x and up not -current as I am, so there can be differences. -- Vallo Kallaste vallo@matti.ee To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-smp" in the body of the message
