Thanks for the idea.
I wonder if Mark Waddingham or one of the other wizards at RR could
create a simple function "online()" that would do some clever, simple
network operation and return network status without EVER hanging?
I know it's possible, Apple's network utility does this, for example.

If this is true, rather than using "ping" in the process, we are
thinking it might be better to issue an FTP command to test
downloading of a small test file. If this fails, we would know that
Revolution downloading will not work.
Again, if we can solve this, it means a huge breakthrough for
Revolution- being able to auto-update, for example, without the
risk of hanging.
As Andre said, ping acts differently on each system - to the extent
that my system (Windows Vista Home Premium) gives an error ("Bad
option -c") for your originally suggested command.
You will probably encounter a similar probelm of ftp not being
available, or allowing different options, or allowing/not allowing
the definition of username/password in the command line, or ....
with this idea.
I'd get around that by creating a simple, tiny Rev-based standalone
that does the ftp download of the test file and monitoring its
progress in the other process; then it sounds like a rock-solid idea.
