USB-to-serial adapter configuration

[Saifi Khan]

Hi all:

How does one configure settings for  USB-to-serial adapter in FreeBSD ?

The one i have purchased is 
http://www.usbgear.com/computer_cable_details.cfm?sku=CHEAP-SERIAL&cats=199&catid=482%2C1303%2C199%2C461%2C106%2C1009%2C601

On the Gentoo box, 'lsusb' displays it as:
 Bus 002 Device 003: ID 067b:2303 
 Prolific Technology, Inc. PL2303 Serial Port

i have to access a headless AMD64X2 box running FreeBSD 7.2-STABLE, 
from a FreeBSD 8.0 laptop.

So far, i've used 'cu' and '/dev/cu0a', but thats because both
the systems had a serial port interface.

The key info i'm looking for is:
 . what is the driver to load
 . what is the device entry to look for
 . is 'cu' good enough or i need to install some other tool


thanks
Saifi.
