I don't think that this will work. imp can say for sure, but I think you would need to completely switch to OLDCARD to use pccardc and that won't work with CardBus cards. I think your stuck with pulling the plug before suspending. (You can plug it right back in. It will sty suspended.) -- R. Kevin Oberman, Network Engineer Energy Sciences Network (ESnet) Ernest O.
