National Replacement Characters

National Replacement Set

Available only when, from the Terminal Setup dialog box, ISO-Latin 1 or DEC Supplemental is specified as the Host character set.

Select one of the 12 national replacement character sets built into InfoConnect. National replacement sets are used in 7-bit operating environments, when characters from the supplemental character sets cannot be accessed by 8-bit codes. Each national replacement set replaces certain characters from the ASCII set with accented characters and symbols for a specific national language.

Use NRC (7-bit) Set

In an 8-bit operating environment, you can enable a national replacement set with this option.

Answerback message


Answerback message

If the host expects an answer in response to an ENQ character, type the answer here.


Insert special characters

Select to allow escape sequences and ASCII control codes in the message (for example, press Enter to include a CR character).


Auto answerback

Select to cause the answerback message to be sent to the host automatically after a communications line connection. You may transmit the answerback message at any time by pressing Alt+F7 (this method of sending the message replaces the VT320 keystroke Ctrl+Break).



Click to clear the answerback message.



Click to replace the message with the word <Concealed>. Once a string is concealed, there is no way to unconceal it; you have to replace the text by typing new text, or click Clear to start again.


Serial device to host

Select to maintain a serial connection to the configured port and send any characters received from this serial connection to the existing host connection. This setting is typically enabled by the host application when it is required.



Click to select and configure a serial port.

The Configure button from the Terminal Setup Advanced Options dialog box is equivalent to the Configure button from the Logging Settings dialog box. You can use the button from either dialog box to configure your serial device port.

Custom DA response

Select to enter a custom Device Attributes (DA) response and then type a sequence for the response in the field below.

The terminal sends this string in response to a primary device attributes request.
