TERMINAL/FALLBACK Displays TFF statistics about a specific terminal. The /FALLBACK qualifier is required, but you can place it before or after the terminal-name parameter. Format: SHOW TERMINAL /FALLBACK [terminal-name]
1 – Parameter
terminal-name Indicates the target terminal for the show operation. If excluded your own terminal is used. Note that you can only use TFF from local terminals; you cannot use terminal fallback on a remote terminal (RTAx), the fallback terminal device (FBA0), a Packet Switch Interface (PSI) terminal (NVA0), a disconnected virtual terminal, or a terminal set for dynamic switching (DYNSWITCH) with DECnet.
2 – Qualifiers
2.1 /ESCAPE_STATE
/ESCAPE_STATE Displays information about escape sequence parsing, and triggering Read Only Menories (ROMs). Use this information to debug your application.
2.2 /FLAGS
/FLAGS Displays which TFF terminal flags (options) can be set by the user and displays any internal TFF flags.
2.3 /FULL
/FULL Displays full information about the terminal. You cannot use this qualifier with /ESCAPE_STATE or /STATISTICS.
2.4 /STATISTICS
/STATISTICS Displays statistics about the specified terminal.
2.5 /TABLES
/TABLES Displays THE names of tables assigned to the specified terminal, including auto-compose keys for the fallback table.
