Sniffing the serial port?

[Bradley Miller]

Hmm -- I'm interested in more serial port projects, but I'm wondering what
exactly is going down the pipe from some of my software to the various
devices I have.  On of them is a Sharp SE-300 PDA -- which I love, but
unfortunately it doesn't have any support on the Windows platform . . . let
alone te Linux one.  Is there a clever way of sniffing what info is being
sent down the COM port?

Hmm ?
