Assuming the serial controller on that board is supported by Linux, when 
you plug in the device to a computer running a recent distribution, 
you'll get a device called /dev/ttyUSB0, which you can use like an 
ordinary serial port.

OTOH, you might instead try a modem that is not a pile of junk.  I 
bought a Motorola SB6120 a month ago, for use with Comcast, and I've 
been quite happy.
