I've never seen any.  DOS was dead as a commercial product before
winmodems came about, and there was no reason for anyone to try to
create a driver.

It should be easy enough to score a USR or the like off eBay.

And you face the paucity of generic USB drivers for DOS.  USB also
came about after DOS was dead.  I don't believe the USB drivers I'm
aware of support the needed features.

I'm not, and more modem information can be found here:

But the biggest challenge is likely to be "What do you call if you
*can* get a working modem?"
