I have a program FAXstf Pro on my computer that I use to send faxes, but it is unable to read a fax I recently received, and this program uses a telephone to USB adaptor in order to send and receive the faxes. in order to read this fax, i need to be able to send it back from my program through the USB line, but instead of a phone cord plugged into the adaptor the manual says I need to take an ethernet cord, plug it into the adaptor, and plug the ethernet back into my computer. When it is sent back to my computer on the ethernet cable I need to open it up in a web browser to read the fax. How do I open the file?
