Here's what Freshmeat.net came up with for 'serial port sniffer':

Linux Serial Sniffer
SLUGer - September 28th 1999, 04:01 EST
The Linux Serial Sniffer allows you to sniff serial data up to 460Kbs via
a Comtrol RocketPort or to 115Kbs using the standard ttyS0 and ttyS1 ports.
Sniffed output can be captured to disk or displayed directly on screen. A
user filter is included to assist specific customisation. The Linux Serial
Sniffer can selectively operate in either a "ghost mode" where there is no
data flow time impediments, or via a "capture and forward mode", where the
user can flexibily intercept and extend the data stream to suit from either
direction.

Depends on:
Using two free serial ports (ttyS0 and S1 in cli mode for example).
It's a 57K download, most of which is an encapsulated postscript file.
There's only about 15K of code, <600 lines. Shouldn't take too long
to figure out. =-]
