Module Name:

  sndthrd.c

Abstract:

  This module:
    1) Verifies a tiff
    2) Enables or disables the FaxRcv Routing Extension
    3) Callback function for the change of state during the RAS connection process
    4) Sends a RAS call
    5) Sends a fax
    6) Receives a fax
    7) Thread to handle the Send logic
