Synopsis:
   $isencrypted(<server refnum>)

Technical:
   * This function returns 0

Practical:
   The EPIC-SSL client's version of this function returns 1 if the connect
   to server <server refnum> is encrypted (via SSL).  EPIC's version always
   returns 0 because it does not support SSL server connections.  Call this
   function before if your script needs to behave differently for SSL
   server connections.

Returns:
   The return value is always zero (0).
