Free, huh?   Hmmmm....   By TCP/IP, do you mean ethernet?  If so, check out
WireShark (http://www.wireshark.org/).  For USB, what platform??  Maybe
the Usb Sniffer for Windows? (http://sourceforge.net/projects/usbsnoop)
For serial, again, what platform?  For Linux, there's the Linux Serial
Sniffer. (http://freshmeat.net/projects/linuxserialsniffer/)

You really should give more info about what platform(s) you intend to use,
and what kind of sniffing you want to do on the USB and RS232 lines??

TCP/IP - Ethereal
USB - not easy
RS232 - any terminal program

Of course, you only want to do this for legitimate reasons. Naturally.
