https://invisible-island.net/xterm/ctlseqs/ctlseqs.html#h4-Functions-using-CSI-_-ordered-by-the-final-character-lparen-s-rparen:CSI-Ps-c.1CA3

Responses include \e [ ? # # c 6 for base ctl seq plus term type e.g. 64 from 
mintty; plus ";" separated attributes up to 7 (round to 8) each single digit and 
8 double digit => 6 + 16 + 24 <= 46
e.g. for mintty \e[?64;1;2;4;6;9;11;15;21;22;28;29c => 6 + 10 + 18 = 34

Could default to column width if longer to allow room for prompts and titles; 
max parameter value lengths are 5 digits; text strings may be longer; querying 
8/16/88/256 colour palettes or similar could require more space.

WSL should work on ARM and reports of uname say aarch64.
