  * -----------------
+ *     12-May-99 added a feature to read data to be sent from a file,
+ *     if the send string starts with @.  Idea from gpk <gpk@onramp.net>.
+ *
  *     added -T and -U option and \T and \U substitution to pass a phone
  *     number into chat script. Two are needed for some ISDN TA applications.
