Advanced 3270 Telnet Dialog Box (Printer Sessions)

Getting there

The options are:

Terminal ID

This setting is not available when configuring Telnet Extended sessions.

Specify a terminal model only if you are unable to connect to the host using the available Model ID settings from the Session Setup dialog box.

If the host can't recognize the specified Telnet Terminal ID string, you may have difficulty connecting, or, once connected, you may experience emulation problems.

Telnet location

(Optional) Type up to 41 characters of descriptive text to provide information about your session. For example, you might include your PC's location, computer name, or IP address.

This features uses the SEND-LOCATION option supported under Telnet connections (RFC779).

Reflection does not initiate a WILL SEND command unless you activate the Telnet location option by typing information in this box.

Response mode (Telnet Extended)

Select to send a response from the PC each time a message is received from the host.

For improved performance, clear this option.

Send Keep Alive packets

Select to provide a constant check between your session and the host so that you become aware of connection problems as they occur.

Choose one of the three types of keep-alive packets:



To cause



The TCP/IP stack to keep track of the host connection. This method requires less system resources than Send NOP Packets or Send Timing Mark Packets. However, most TCP/IP stacks send Keep Alive packets infrequently.

Send NOP Packets

Reflection to periodically send a No Operation (NOP) command to the host. The host is not required to respond to these commands, but the TCP/IP stack can detect if there was a problem delivering the packet.

Send Timing Mark Packets

Reflection to periodically send a Timing Mark Command to the host to determine if the connection is still active. The host should respond to these commands. If Reflection does not receive a response or there is an error sending the packet, it shuts down the connection.

Keep Alive timeout in seconds

Select the interval between the keep-alive requests. The range of values is 1 to 9999 seconds; the default value is 600 seconds.
