The modems were fairly proprietary. While being obviously standard (with typical components).
However, there are two ways. You can take the board out and flip it over to look at the main IC, which may shed some light. However, the modem on my T3100SX had even more sparse info. Just dead links for the IC.
Also, windows can detect the modem and usually makes the right choice. On my T4400C, even though I couldn't find info on its modem (other than being a 2400baud modem) windows loaded it as a Hayes Smartmodem 2400, and it worked flawlessly.
Also, the modem doesn't have a speaker. It instead uses the PC speaker.
