                          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

     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
     (value is S)                              Receive 32 bits of data
                                               from link l (value is S)

     CLS, L, U                                 CLS, U, L

     STR, S+1, U, B                            STR, U+1, S, B

l , l , and l  are links, m  and m  are message allocations, b
 A   B       c             B      c                           B
and b  are bit allocations, and all other symbols are as defined in
RFC 123.
