Controlling Telnet server functions from the client

You can use the Telnet client to control workstation processing on the Telnet server when you are in a client session.

Both the i5/OS^® name and the TCP/IP name are listed for each of the command functions.

To select which server functions that you want to control, you need to access theTelnet Control Functions menu. To get to this menu, press the Attention key on your 5250 keyboard.

The following list provides you with a brief description of each Telnet client control function:

• Interrupting a process on the system Interrupt process or IP: This function cancels, interrupts, or suspends a process that has started on the server. For example, you can use IP when a process appears to be in a permanent loop, or if you have started a process by accident.

• Querying connection status when the system becomes inactive Query connection status or AYT: This function provides a message from the server that lets you know that the system is still running. You can use this control function when the system is unexpectedly inactive for a long period of time.

• Discarding remote output before it reaches your workstation Discard remote output data or AO: This function allows a process that is generating output to run to completion without sending the output to your workstation. This function removes already produced system-system output that has not yet displayed on your workstation.

• Clearing the data path between your system and the server Clear the data path or SYNCH: This function discards all characters (except Telnet commands) between your system and the server. You can use this function when the network's flow control mechanisms cause other functions, such as IP or AO, to be buffered.

• Ending the Telnet session End Telnet session or QUIT: This function ends the Telnet session and closes the TCP/IP connection to the system (remote system). You can request this function any time during the Telnet session, but you should sign off the remote system before selecting this function. If you do not sign off, you remain signed on to the system because the Telnet protocol does not provide an end session sequence.

• Using the Attention key to remote host option ATTN key to remote host: Press the Attention key to display the Telnet Control Functions menu.
