a similar, simple mechanism is desirable for the ICP.
Furthermore, the ICP should allow for simplex as well as
duplex connections from user to server.
The following commands are necessary for simplex
connections:
ISC - Initiate Simplex Connection
ASC - Accept Simplex Connection
RSC - Refuse Simplex Connection
The notation for parameters is similar to that
of RFC #165:
L - Server socket name, in one special case the
server is "logger".
U - User socket.
S - Socket assigned by server for the connection
with user.
X - Is the byte size if U is odd and is the link
number if U is even.
- -
X - Is the complement of X (X is the link number
if U is odd and byte size if U is even.
To initiate a simplex connection the user's NCP
issues:
ISC, L, U, X
To refuse this connection the server's NCP issues:
RSC, L, U
