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

     STR, L, U, 32                                         A

Send 32 bits of data
in 1 message on link l

                                               from link l (value is S)
                                                          A

l , l , and l are links, m and m are message allocations, b
 A   B       c             B      c                           B
