I have a pci modem that won't dial. It's an ESS ES56H-PI Data Fax Voice Modem from Pine Group. Is it possibale to make it work?

Take a look at www.linmodems.org, I've heard they've got some good resources. Sorry can't help you more, never messed with modems much.

Thanks for the help but unfortunatly it doesn't look like it will work.
another great resource is the website http://www.idir.net/~gromitkc/pci_list.html.
It has fairly extensive list of pci as well as other types of modems.
