The Linux-based OS "Debian" ships with a package called 'snooper',
which reads as if it could fulfill your needs:

$ apt-cache show snooper
Package: snooper
Priority: optional
Section: comm

Description: Captures communication between two external serial devices
 Snooper passes data transparently between two serial (RS232C)
 devices, capturing and logging the data and occasional comments you
 want to insert into the logs.
 .
 It is useful for debugging or analyzing the communications protocol
 between two devices that would normally be connected directly to each
 other, e.g. a digital camera and a personal computer.  By sitting
 "in the middle" (after you connect the two devices to serial ports
 on your Linux machine) snooper is able to capture data traveling in
 either direction while also passing it unmodified to the other device.
 .
 It is also possible to operate with a single serial device, using
 your console and keyboard as the second device.
