If answer is only : mailed to me I will post it to these groups. The ESP card will work--but only in 16550 mode. I tried it with the 1k buffer enabled, and it rather annoyed FreeBSD. I didn't expect it would help any in FreeBSD, but I got it to use in the enhanced mode under Windows, and 16550 mode under FreeBSD. The problem is that if you run windows and then do a soft reboot and run FreeBSD, you're hosed. It will be in the enhanced mode. It seems that you have to reconfigure the card and hard reset. I don't think that it's worth the hassle. Loren
