   3:  *  Rev 5-25-89
   4:  *  This file contains GEnie specific code for setting terminal modes,
   5:  *  very little is specific to ZMODEM or YMODEM per se (that code is in
   6:  *  sz.c and rz.c).  The CRC-16 routines used by XMODEM, YMODEM, and ZMODEM
   7:  *  are also in this file, a fast table driven macro version
   8:  *
   9:  *   This file is #included so the main file can set parameters such as HOWMANY.
  10:  *   See the main file rz.c for compile instructions.
