At a command prompt type perldoc -f sysopen and perldoc -f open. Or compare them on http://perldoc.perl.org/index-functions.html.

My summary is that sysopen is a lower-level interface that can't ever be removed because of backwards compatibility, while open is the one that I would suggest people use.
