Compatibility PCI Fax Card with Freebsd

[OXx]

Hello all,

I have a Rockwell International HSF 56k Data/Fax/Voice/Spkp (w/Handset)
Modem (rev 01)  or a Rockwell International HCF 56k Data/Fax Modem (rev 01)
I would like to know if Someone have experiance with theses olds PCI
Cards...
In fact I would like to implement a hylafax server and the linux driver is
not free and not sure it works.
Is it compatible with freebsd to do Fax ?

Thans
