OS/2 NDIS Hot-Pluggability and Suspend/Resume
You can remove the card or go into suspend mode at any time as long as you are not running any applications that use shared resources. After you reinsert the card or resume, you should have all of your LAN shared resources connected. If you use CM/2 to connect to the host, you will have to log on again.
One scenario that does not work is suspending and then removing the card. The card will not be recognized when it is reinserted. If you want to do something like this, you must first remove the card and then suspend. You can then resume later and reinsert the card later.
