No, it's a USB modem, winmodems are a type of PCI modem.

There is, I've used one.  While I can't gaurntee it will work, check out
the umodem driver.  Just load the driver with 'kldload umodem' and see
if it detects anything.  dmesg is a handy command for such things.
There are also some other possibilities, check out
http://www.freebsd.org/releases/6.1R/hardware-i386.html
under USB.  The device probably will be something like /dev/ucom0, but
check the output of dmesg.

Any serial modem should work fine for FreeBSD using either the hardware
serial ports on your motherboard with the sio driver or possibly some
USB serial adapters that are supported.  USB modems are not winmodems,
but they still sometimes require a special driver that FreeBSD does not
have.
