In days of yore I used to run a cable between two computers'
serial ports, crank up Laplink and transfer files to my heart's
content. Is there a freeware program to do this? Maybe with a
USB connection?
Win XP SP2
This functionality is part of the Windows OS since Win95. It is
called 'direct cable connection'. Look here for setup instructions:

You need a so called Laplink-cable/adapter for parallel or seriell
connection, though. (Some pins are crossed.)
Likewise you would need a *crossover* USB cable for direct connection.
Be aware that they are somewhat expensive. Maybe you would even be
cheaper and better off with 2 Ethernet cards and a cross-over ethernet
cable.
Crossover USB cable are 'intelligent'. Most come with their own
software to connect 2 PC's. Else you'll use a kind of network setup.
For connection via Ethernet you also would setup a network instead
of using the 'direct cable connection' functionality. Other types of
connection (infrared for example) are also possible.
There are lots of resources on the web on this topic. Maybe you scan
through these tutorials:

From a quick glance they are comprehensive and straight forward.
