I grew fond of printing a char, after I spent some time snooping a uart. The o-scope in capture mode (I realize this wasn't always an option) grabs the char. Handy because I find char waveforms very easy to recognize at just a glance, and you don't have to measure periodicity or count toggles. Even if you don't have a uart, you can write a little proc to bit-bang a pin.
