This driver has been hard to find. The zoltrix site has no links to it. Everybody that has the modem in Win98 should know that you need a modem enumerator to get your modem to install. In Win2000 i though you needed the same but this seems to work. Install this as the Simple PCI Communications device. If it doesn't work then either find an AOpen software modem driver, install that and then overwrite the driver (it worked for me!) or e-mail me.
