5       Feature negotiation failed to detect prescience of another error-control     

        modem at the remote end.                                                      

6       Other error-control modem did not respond to feature negotiation message sent 

        by this modem.                                                                

7       Other modem is synchronous-only, this mode is asynchronous only.             

8       Modems could not find a common protocol.                                     

9       Modems could not find a common protocol.                                     

10      Feature negotiation message sent by remote modem is incorrect.               

11      Synchronous information (data or flags) not received from other modem. Modem 

        waits 30 seconds before hanging up.                                           

12      Normal disconnect initiated by remote modem.                                 


13      Remote modem did not respond after many transmissions of the same message,   

        modem attempts connection 10 times before giving up.                          


14      Protocol violation occurred.                                                 

15      Compression failure.                                                         

16      Speed indicated by S37 did not match any of the speeds indicated by S109.    

17      Hangup was due to S116 timeout.
