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 dgl@dlee.org SSB + BART Group doug.lee@ssbbartgroup.com http://www.ssbbartgroup.com "A mailing list is a crude but effective cross between a chain letter and a shouting match." -Andrew Kantor
