Checking for UDP availability

[ourobolus]

I'm using a Garmin GPS system to stream data to my computer through a UDP stream. The script I have runs fine when the device is attached and enabled, but when it isn't, the script merely continuously checks for the UDP data rather than realizing that it isn't sending any data. If this were TCP, it would be simple enough to determine a connection, but...eh.

use IO::Socket::INET;
my $MySocket = IO::Socket::INET -> new(LocalPort=>3944, Proto=>'udp');

That's my current setup, but I'd like to figure out some form of error checking that would allow the program to run regardless of the UDP connection.

Thanks.

Not really sure if this fits your problem, but the general rule of the thumb is to use IO::Select or IO:oll with a timeout and then check the flags for errors, data, etc. Because of the timeout your programs runs (in a loop) regardless of anything.
