The serial port will only be rarely used, and the chip controlling it
can be replaced. The lines that will be in continuous use have
strong

I can't imagine why you would want one on either TX or RX... I have
never had any issues with RS232 on any board I have designed. My biggest
RS232 issue is usually finding a computer that has a serial port
stupid laptops and their serial port exclusion

What's a good size ferrite to use on an rs232 line? I've got a spot
for a set of 0603 ferrites on my serial console lines, but I have no
idea what size (uH) ferrite to use.
The ferrite bead impedances are usually specified by a graph showing
both the resistive and reactive
