SNMP Traps - can I monitor them?

The opensockets() function shows I have other sockets open, but 162 never
gets opened.  Also no socketerror message is received,  it just doesn't do
anything!

I'm on OS X on a Mac, I keyed netstat -a into the terminal on OS X and it
gave lots of interesting stuff but nothing to indicate my port 162 was open.
I'm well out of my depth anyway.  I don't think I need to monitor traps any
more, I've just noticed my APC UPS sends datagrams every 26 seconds, but if
something important happens it sends a datagram immediately...and there's me
thinking I'd need to get a TRAP from it.  So I can program my whole system
just listening to datagrams.

My next problem is knowing if I can ping an IP number just to see whether it
exists before I try and open a separate communication channel to it?
