The system software does include software which enables it to use standard Type II modem cards. However, the Global Village Platinum Pro and other "combo" cards need additional software to be recognizable by the PowerBook computer.
"Combo" or combination cards include cards that have functionality in addition to being a modem, such as Ethernet. These cards require additional software to be recognized by the computer even if you are just using the modem and not using the Ethernet or other capabilities. In addition to Global Village, some examples of the other vendors making these types of cards are Farallon, Dayna and Asante.
To resolve this situation, you simply need to install the software that came with your PC card. After you install the necessary software the card should be functional again.
