What “Not Supported” Means

Testing Terminals for Compatibility

NOTE

Strictly speaking, a terminal is not supported if it has not been rigorously tested with the Display Terminal Interface. There are several HP terminals which may be compatible with the terminal interface. Terminals such as the

DEC® VT100® , DEC® VT220® , and WYSE ® WY-50, or emulations of these may also work properly with the terminal interface. If you have one of these terminals, try it. Here is a list of terminals you should try.

HP 2392A

HP 2394A DEC® VT100® DEC® VT220® WYSE ® WY-50

HP AdvanceLink terminal emulation software (configure as HP 2392A)

Here is how you test an unsupported terminal for compatibility with the Display Terminal Interface:

1.Connect your terminal and configure its communication parameters to match the mainframe’s serial interface (see Appendix C)

2.With your terminal turned on and set to “remote mode”, turn on the mainframe. After the mainframe power-on self-test, the display interface sends sequences of characters to your terminal which should cause it to return its identification. If the terminal ID matches one in a list kept by the terminal interface, it will send character sequences to program the function keys and their labels.

3.If you now see the “Select an instrument” prompt and the “Select an instrument” menu labels, your terminal is ready to try. Go to the beginning of this chapter and try the menus.

4.If you see only the “Select an instrument” prompt without the “Select an instrument” menu labels, your terminal did not return a recognized ID. To set the terminal type manually, type the Terminal Interface Command:

ST HP (followed by Return for HP terminals)
or
ST VT100 (followed by Return for VT100®	emulators)
or
ST VT220 (followed by Return for VT220®	emulators)
or
ST WYSE30 (followed by Return for WY-30®		emulators)
or
ST WYSE50 (followed by Return for WY-50		emulators)

You can type "ST" without arguments at the "Select an Instrument" menu. The display terminal will attempt to identify the terminal that is connected. This is particularly useful if you are hooking a terminal to a system which already has power, since you do not need to cycle power and wait for the system to reboot.
