Lack of serial ports on laptop yes; the FreeBSD hardware hasn't been chosen yet, but I predicted difficulty getting a modern machine with a serial port.

So the problem is a lack of serial ports on your laptop "terminal", not on the FreeBSD machine? That sounds easier to work around than the other way around. There are some other possibilities, but I don't think they will work as early in the boot process. I *think* you can use a USB serial port as a console, but the loader doesn't seem to understand it. There's also dcons(4), but that needs firewire, and I don't know if that knows how to talk to anything on a Windows machine. Good luck; sorry I can't be more help. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

More simple once found at least. :-) > What do you hook up to that serial port, anyway? A desktop Windows machine with a serial port, until said machine suddenly ceased to function entirely. Now it would be a laptop with a USB-to-serial adapter except the one I bought also seems unwilling to function. I tend to run short of PCMCIA slots for such things on my laptop, my one-and-only PCMCIA slot being occupied pretty permanently by an EVDO card. Sounds like I'll need a *functional* USB-to-serial adapter on the laptop end, an actual serial port on whatever new box of parts ends up running FreeBSD 6/7, and my old trusty null modem conglomerate of cable and adapters. I guess I'll collect recommendations for a good USB-to-serial adapter. I've seen prices range from around $30 to around $120.00 if memory serves, and the last one I bought was closer to the former. -- Doug Lee [EMAIL PROTECTED] SSB + BART Group [EMAIL PROTECTED] http://www.ssbbartgroup.com "A mailing list is a crude but effective cross between a chain letter and a shouting match." -Andrew Kantor ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

I am not sure, but I would expect that you would need BIOS support for something like that. Personally, I would stick with serial ports as long as possible, because they are much more simple than any alternatives. What do you hook up to that serial port, anyway? Sorry I can't be more helpful, but I wanted to make sure you got *some* help.
