Viewing output of multiple comm ports - Similar to Hyperterminal

[ericssonboi]

I'm trying to view the output of a multiple comm port like l would be able in Hyperterminal.  I've verified that the attached file works with a single comm port, but i'm having difficulty integrating it to view different outputs of differnet comm ports all at once.  Ideally i'd like to view 3 different comm ports all at once.  Any help appreciated,

in a loop scan each port.

make an array of visa resources

and scan for bytes at port and if so read them.
