A station set for TCP/IP access defines a set of ASCII emulation characteristics and an optional host IP address. The 3174 TCP/IP Telnet Support supports the following ASCII terminal emulation:
• DEC VT100
• IBM 3101
• DG D210 (USA English only)
• DEC VT220, 7-bit control
• DEC VT220, 8-bit control
Each TCP/IP station set you define will be displayed on the host Connection Menu for the terminal user to select as a connection.
For each station set definition, you may specify an IP host address, or use the default response (all zeros), in question 790. Your response is used as follows:
• If you specify an address, the 3174 does not automatically connect to that address when the station set is selected from the Connection Menu. The address is used if the user issues a. PING or an OPEN command without specifying a destination;
Chapter 3. Adding 3174 to TCP/IP Network 33
• If you do not specify an address (default all zeros), then the user will need to specify the destination when issuing the PING or the OPEN command.
So, if your users at the 3270 coax terminals will use the 3174 TCP/IP Telnet Support to access only one TCP/IP host and that host supports DEC VT100 devices, then you only need to define one TCP/IP station set (the DEC VT100 station set). You will specify that host's IP address in question 790 so that the users do not have to remember it. To access that host, the user selects the DEC VT100 station set from the Connection Menu, which puts the display into local mode, and then issues the OPEN command without specifying a destination.
If your users will access more than one hosts, you probably should define five TCP/IP station sets, one for each type of ASCII Emulation supported. This allows the users to select the required station set from the Connection Menu. Again, if you specify an address in question 790, it will be used when the user issues a
PING or OPEN command without a destination. If you do not specify an address in question 790 (default all zeros), then the user will need to specify the
destination when issuing the PING or OPEN command.
For our example, we have defined five station sets (station set numbers 3 through 7 in the following panels) for TCP/IP access. Station set number 3 also has a "default destination" customized in question 790. Station set number 8 defines 3163 displays that are attached to the 3174 AEA; they can also select the TCP/IP connections from their Connection Menu.

To define each station set for TCP/IP access, respond to the following questions:
Q721 Enter a station set name that you wish displayed on the Connection Menu.
Q722 Enter TH as the station type for the TCP/I P host.
Q751 Specify the data stream supported by the TCP/IP host:
• 1 = DEC VT100
• 2=IBM 3101
• 3 = DG 0210 (USA English only)
• 4 = DEC VT220, 7-bit control
• 5 = DEC VT220, 8-bit control
Your response to this question only affects the operation of 3270 displays. It determines the type of ASCII emulation that the 3174 provides for the 3270 display when the user selects this station set as the destination. When the user at an ASCII terminal selects a TCPIIP destination, the value of this field is ignored.
Q761 Respond only for VT100 or VT220 data stream, that is, if question 751 = 1, 4 or 5. The valid responses are:
• 0 = Auto XON/XOFF disabled.,
• 1 = Auto XON/XOFF enabled (default response).
Q762 Respond only for VT100 or VT220 data stream, that is, if question 751 = 1, 4 or 5. The valid responses are:
• O=Wraparound option disabled.
• 1 =Wraparound option enabled (default response).
Q763 Respond only for VT100 or VT220 data stream, that is, if question 751 = 1, 4 or 5. The valid responses are:
• 0 = New line option disabled.
• 1 = New line option enabled (default response).
Your response to this question depends on the host applications you will be using. If not answered correctly, characters may be placed in the wrong positions on the screen. When set to 1, the 3174 treats a line feed character from the host as a new line (line feed followed by carriage return).
Note: For connections to RS/6000* hosts, question 763 should be O.
Q764 Respond only for VT100 or VT220 data stream, that is, if question 751 = 1, 4 or 5. The valid responses are:
• 0 = Margin bell disabled.
• 1 = Margin bell enabled (default response).
Q765 Respond only for VT100 or VT220 data stream, that is, if question 751 = 1, 4 or 5. The valid responses are:
• 0 = DEC host ASCII character set is NRC (default response).
• 1 = DEC host ASCII character set is MCS.
Q771 Respond only for IBM 3101 data stream, that is, if question 751 =2. The valid responses are:
• O=Automatic line feed disabled.
• 1 = Automatic line feed enabled (default response).
The receipt of a carriage return from the host will cause a carriage return and a line feed at the terminal.
Chapter 3. Adding 3174 to TCPIIP Network 35
Q772 Respond only for IBM 3101 data stream, that is, if question 751 =2. The valid responses are:
• 0 = Enter causes a carriage return only.
• 1 = Enter causes a carriage return and a line feed (default response).
Q773 Respond only for IBM 3101 data stream, that is, if question 751 =2. The valid responses are:
• o
= Automatic new line at column 80 disabled.• 1 = Cursor automatically moves to the first position of the next line after reaching column 80 (default response).
Q774 Respond only for IBM 3101 data stream, that is, if question 751 = 2. The valid responses are:
• O=Scrolling disabled.
• 1 = Scrolling enabled (default response).
Q775 Respond only for IBM 3101 data stream, that is, if question 751 = 2. The valid responses for the line turnaround character to be used are:
• 0 = Use EOT{end of transmission).
• 1 = Use CR (carriage return) (default response).
• 2 = Use XOFF (transmit off).
• 3 = Use ETX (end of text).
Q790 Enter the host IP address that is the default destination for the 3174.
You may leave the response at its default value (all zeros). The user will need to specify the destination when issuing the PING or the OPEN command.
If you do specify an address, the 3174 attempts to connect to that address as the default destination or when this station set is selected from the Connection Menu.
You can leave all other responses at their default values.
