Evidently I'm really missing the boat.  I've been trying to find the
well-known port for ICMP.  Is there no such thing?

There are no well-known ports for ICMP simply because ICMP doesn't use
ports. There are only the different ICMP-typecodes (dest. unreach, redirect,
echo request/reply, ...). 

Regards,
