  Add the vendor/product codes to "pcidevs" in /sys/dev/pci.  Then
rebuild the corresponding .c/.h files using 'make -f Makefile.pcidevs'. 
Chances are good that the device acts like a normal serial
communications (UART) device.  To make this work, add an entry for your
modem to 'pucdata.c' (also in /sys/dev/pci).  Then configure/build a
kernel with

puc*    at pci? dev ? function ?  # PCI "universal" comm. cards
com*    at puc? port ?            # 16x450s on puc boards

  If this works, please include your changes in a PR so this can be
added to the kernel ...

  Cheers
