[REBOL] Error handling

[a2dfc]

What is the proper way to detect an error when opening a port? For example,

   check-port: open tcp://www.texastech.edu:1234

returns an access error. Can I detect this error in a script without the
session quitting? My goal is to send e-mail if a port is unavailable.
