Look for ltmodem and linmodem.  If you are very lucky, it is for that
generation of softmodems.  But last time I checked, it was for 2.6

I'd get a real modem.

It is bad enough you'll waste a lot of CPU on crap USB-RS232 conversion,
running a full V.92 stack in kernel mode at RT priority on top is too
annoying for words.
