DECRPSS—Report Selection or Setting
The terminal sends the host this sequence in response to a request selection or setting (DECRQSS) sequence. The terminal sends DECRPSS to report the setting of a particular control function.
Applications can use the information in the DECRPSS report to save the current selections or settings of some control functions. Later, the application can restore the control functions to their saved state.
This operation is useful for applications that need to temporarily change the settings of some of the terminal's control functions. When the application is finished, it can restore the control functions to their previous state.
|D ... D
indicates whether or not the request from the host is valid.
|0||Host's request is valid.|
|1||Host's request is invalid.|
D ... D
indicates the current setting of a valid control function that the host asked about. D...D consists of all the characters in the control function, except the CSI (9/11) or ESC [ (1/11, 5/11) introducer characters.
The host requests the setting of the select graphic rendition (SGR) function. If the current graphic rendition is underline, blinking, and reverse, then the terminal responds with the following DECRPSS sequence:
DCS 0 $ r 0 ; 4 ; 5 ; 7 m ST
0 ; 4 ; 5 ; 7 m are all the characters in the SGR sequence, except CSI.
The host requests the setting of the set top and bottom margin function (DECSTBM). If the current top and bottom margins are set to include the complete screen area (24 lines/screen), then the terminal responds with the following DECRPSS sequence:
DCS 0 $ r 1 ; 24 r ST
1 ; 24 r are all the characters in the DECSTBM sequence, except CSI.
The host requests the setting of a function that the terminal does not recognize. The terminal responds with the following DECRPSS sequence:
DCS 1 $ r ST
The terminal does not send a data string (D...D) to the host when the terminal receives an invalid request.
