That sounds quite reasonable. Linux pcmcia services may have an odd way of working their magic, but it does seem to work very well in any respect (as far as compatibility goes with various socket vendors). Given the information available, I think there is a chance to make a nice addition to FreeBSD's pcmcia socket compatibility if this code can be applied in a clean and safe manner. If anybody can do it, I'm sure you can. :) Thanks, Tony Toole ----- Original Message ----- From: "M.
