I cannot get a UC card to work but my CC card is fine
The new range of serial cards available from Brainboxes have the prefix UC, which stands for Universal Card. These cards are able to work in both a 5v and 3.3v PCI slot and are backward compatible with the CC range of PCI cards that Brainboxes have manufactured for many years. In order to support the new cards, the Serial Solutions drivers have been updated for Windows 98, NT, 2000, XP and Server 2003 families, therefore if you are using older drivers, you will need to uninstall and reinstall the latest drivers. These are available from the following web page: Serial Solutions. The uninstall program is located in the root of the folder and is called SSUnist.exe.
