Re: AS/400 IP COMMUNICATION WAIT TIME

[Jim Langston <jlangston@xxxxxxxxxxxxxxxx>]

Short answer: it is not possible to disconnect without the clients
"knowing".

Long answer:
TCP is a connection scheme.  When using TCP/IP the connection
remains open.  Once the communication between the server and
the client is closed, the TCP/IP connection is closed.  UDP, on
the other hand, is a broadcast scheme.  There is no permanent
connection.

Since the majority of IP communication is TCP based (including
client access and the like) if you disconnect the cable from either
the server or the client the channel is closed, and the program
errors out, either graceful with a window saying the session has
been terminated, or ungraceful for programs not looking for this.

Once you disconnected and reconnected, the connections would
have to be re-established.

Jim Langston
