  16. Through the PROCOM (a PC communication software) document I learn that
  17. Kermit uses 24 bit CRC for error detection/correction. Does anyone know 
  18. what is the generating polynomial for this CRC-24? Any reference to 
  19. a list of 24th order CRC generating polynomials will be much appreciated. 
  20.  
  21.  msscom.asm in MS-DOS Kermit:
  22.  
  23. ; The CRC is based on the SDLC polynomial: x**16 + x**12 + x**5 + 1.
  24. This is also known as CCITT-16.
