I have a nifty little hardware gadget called Logic. It's an 8 channel
logic analyzer by a company called Saleae, and it has
Linux/Windows/Mac GUI clients available for it.

It has decoders that can decode async serial. You may need voltage
converters in order to make it work (depends on your HW). It also
works with i2c and spi.

I also have an even cheaper device called a Bus Pirate. It doesn't
need a GUI, you talk to it using a terminal emulator.

It can deal with serial, i2c, spi.
It can deal with wider input voltages without requiring external
voltage converters.

For the more adventurous, there is a 32-channel device called
"OpenBench Logic Sniffer"

I've heard that there are issues getting the UI running under linux.
I have one, but haven't gotten around to using it yet.
