* Returns a report as `CSI Ps; Pm $ y` (DECRPM), where `Ps` is the mode number as in SM/RM
* or DECSET/DECRST, and `Pm` is the mode value:
* - 0: not recognized
* - 1: set
* - 2: reset
* - 3: permanently set
* - 4: permanently reset
*
* For modes not understood xterm.js always returns `notRecognized`. In general this means,
* that a certain operation mode is not implemented and cannot be used.
*
* Modes changing the active terminal buffer (47, 1047, 1048, 1049) are not subqueried
* and only report, whether the alternate buffer is set.
*
* Mouse encodings and mouse protocols are handled mutual exclusive,
* thus only one of each of those can be set at a given time.
*
* There is a chance, that some mode reports are not fully in line with xterm.js' behavior,
* e.g. if the default implementation already exposes a certain behavior. If you find
* discrepancies in the mode reports, please file a bug.
