Yes, there are a exceptions. Also, some pure softmodems work with
"slmodem" driver.

Sadly sometimes you are stuck with the modem you already have and cannot
replace it. In a perfect world, one could choose the best modem for his
needs.

We, at the office, have five of those hardware-based modems (rs-232) and
one Eicon card (isdn, PCI based), we use them for faxing along with
HylaFAX so dial-up modems still have their use. And I would not change
none of those serial modems for a new one featuring USB (I find the
serial port more reliable than USB) :-)
