-// This operator is a convenient way for a sketch to check whether the
-// port has actually been configured and opened by the host (as opposed
-// to just being connected to the host).  It can be used, for example, in 
-// setup() before printing to ensure that an application on the host is
-// actually ready to receive and display the data.
-// We add a short delay before returning to fix a bug observed by Federico
