                          Comments on RFC 123
 


 

The following is my interpretation of the exchange between NCP's which
 

would be necessary to carry out the Initial Connection Protocol of RFC
 

123.
 


 

     Server NCP                                User NCP
 

     ----------                                --------
 


 

     Listen for Connection on L                RTS, U, L, l
 

     STR, L, U, 32                                         A
 


 

     Send 32 bits of data
 

     in 1 message on link l
 

                           A
 

     (value is S)                              Receive 32 bits of data
 

                                               from link l (value is S)
