[Pdx-pm] IO::Socket::INET wakeup call

[Roderick A. Anderson]

Don't we all hate replying to our own posts.

FYI.

Lisa offered some great ideas but a glimmer of light came last night and 
I just checked the driver settings on the Windows machine.  Power Saving 
mode was enabled so the system was shutting the NIC down when inactive 
active.  Hopefully this is the solution.  I'll wait for awhile and try 
it.  Wait again and try again.
