Modem usage for data mode is quite substantially different that for FAX mode; for one, FAX mode is always half-duplex transmission, which drastically reduces the complexity of the audio signals. In addition, data mode frequently wants to use bit rates of 14.4kbps (or higher) where FAX is generally able to work well at 9.6kbps and lower. In short, it is not likely that you will be able to accomplish what you want using an analog interface card, and you may not be able to do it at all, even using a digital interface card and a channel bank. -- Kevin P.
