Configure Connection Settings Dialog Box (5250)

Getting there

From this dialog box, you can specify the settings for a TN5250 connection.


Host name/IP address

Identify the host to which you will connect. Type the host name, alias, or numeric IP address.

Note: Both IPv4 addresses (in the form and IPv6 addresses (in the form 2001:0db8:3c4d:0015:0000:0000:abcd:ef12) are accepted.


Type the host port or socket number that the session should use. This field accepts any number between 0 and 66,535 (default = 23).

Device name

Specify the terminal device name (also called the display name or the workstation ID) that the AS/400 should use for your session. If you leave this box blank, the AS/400 creates a device to use for your session.

The device name can be up to ten characters long. You can include any of the following characters as part of the value in the Device name box.




Replaced by A, B, C, and so on to create a unique device name. If the entire alphabet is used, the generated device names continue with AA, AB, AC, and so on.


Replaced by P for printer sessions and S for display sessions.


Replaced by 1,2, 3, and so on to create a unique device name.


Replaced by the local workstation name, left-trimmed, if the generated name exceeds 10 characters.


Replaced by the local user name, left-trimmed, if the generated name exceeds 10 characters.


Specifies right-trimming instead of left-trimming. Use with &COMPN or &USERN. This character can be placed anywhere in the string.




  • You can use only one string in combination with these characters. If you use separated strings, the second string is dropped. For example, %MyDevice= is valid. However, %My=Device is not valid, and will be treated by the system as if it were &My=.
  • You cannot use both &COMPN and &USERN in the same string.
  • To have Reflection generate unique device names automatically based on the special characters described above, the Generate Device Names setting must be enabled. In printer sessions, this setting is off by default. To enable it, see the Generate Device Names topic.


Automatically connect to the host

Select to establish a host connection as soon as the associated session document is opened.

Automatically reconnect when connection is lost

Select to reestablish a host connection after any disconnection that is not initiated from Reflection.


Model ID

Specify the terminal (also known as a display station) you want to emulate.
