I also have some of these devices (and briefly used pcwl on my old laptop), but I doubt there is a use case for them from going forward. The devices were wildly popular 10 years ago, but for the mobile platforms, that's an eternity. If there are still PCMCIA based systems somewhere, supported PC Cards that are capable of 802.11g should pretty have completely superseded them. -Albert ------------------------------------------- illumos-discuss Archives: https://www.listbox.com/member/archive/182180/=now RSS Feed: https://www.listbox.com/member/archive/rss/182180/21175430-2e6923be Modify Your Subscription: https://www.listbox.com/member/?member_id=21175430&id_secret=21175430-6a77cda4 Powered by Listbox: http://www.listbox.com
