There must be a way to do this but I don't know how. However, there is a
utility at SysInternals called PortMon that will show activity and data
on serial and parallel ports. I don't know how to get it to give you the
data but perhaps you can get them to tell you how they did it.

Link to the utility:
http://www.sysinternals.com/Utilities/Portmon.html

Description:
Portmon is a utility that monitors and displays all serial and parallel
port activity on a system. It has advanced filtering and search
capabilities that make it a powerful tool for exploring the way Windows
works, seeing how applications use ports, or tracking down problems in
system or application configurations.

Portmon works on NT 4.0, Win2K, XP and Server 2003, Windows 95 and
Windows 98.
