It was discussed 1000 times in linux-kernel list. Short summary:
1. WinModem are braindead devices in first place. Thay could work reliable in
RT-Linux but they COULD NOT reliable work in Windows or "standard" Linux
(not belive me? try to run some VERY time-consuming program under Windows
and try to use Winmodem at the same time).
2. Since WinModem is braindead device most manufacturers will not show you
technical documentation. In fact it's not known even one WinModem with
enough for creation of Linux driver technical documentation.
3. So you'll need a lot of reverse ingeneering and such just to got
non-relibale working driver. Bad deal IMO but you could try do this if
you wish.
4. And your driver will work for tiny per cent of WinModems: often even
WinModems from the same manufacturer and with the same model name will be
incompatible on hardware level! Incompatibility will be hided in Windows
drivers of course.
So... Just forgot about this evil creation and use real modem :-)) Almost the
same is true about WinPrinters (1. is not 100% true for them but 2., 3., 4. are
there as well).
