Original Pull Request: https://github.com/microsoft/terminal/pull/14290

State: closed
Merged: Yes

The original implementation of the Device Status Report sequence was
only capable of handling ANSI status queries. This PR adds the ability
to respond to private DEC queries as well.

To prove it's working as intended, I've also included support for the
DEC extended cursor position report (DECXCPR), which is essentially
the same as the ANSI cursor position report, but with an additional
parameter indicating the page number. Until we support paging, though,
that value is just hardcoded to 1.

References

The method for distinguishing between ANSI options and the private DEC
options is based on the updates made to the SM/RM mode sequences in
PR #8469.

Validation Steps Performed

I've added a couple of unit tests covering the DECXCPR report, and
also manually confirmed we now pass the Extended Cursor-Position test
in vttest.

Closes #14206
