+# This identifies as a VT220 with 4=sixel and 22=color, however:
+# tack:
+# bell does not work
+# status-line does not work because foot does not set the window title
+# sends escape when meta key is used, whether or not smm/rmm enabled
+# vttest:
+# wrap-test fails
+# no application-mode for numeric keypad (unless private mode 1035 is set)
+# no NRCS
+# no VT52
+# no SRM
+# protected areas do not work
+# SU/SD work, SL/SR do not
+# DECRPM responds, but not the corresponding ANSI reports.
+# otherwise few reports, except cursor-position and mouse and some dtterm
+# VT520 cursor-movement works, except for left/right margins
+# supports xterm/DECSCUSR, though default case in vttest does not blink
+# Send: <27> [ 0 <32> q
+# Text: The cursor should be a blinking rectangle
+# partial support for xterm mouse any-event mode and button-event mode:
+# + does not report focus-in/focus-out
+# + does not report buttons 6/7

+#
+# General:
+# + written in Rust.
+# + initial screensize is odd, i.e., 81x24
+# provides no visual feedback on resize
+# ignores "resize -s"
+# manual resize and then running resize got off-by-one adjustment
+# + leaves debris (unerased cells) when switching between normal/alternate
+# screens.
+# + sets TERM=xterm-256color
+# tack:
+# + misplaced message in "am" screen
+# + fails xenl (should be false)
+# + cvvis is same as cnorm, block
+# + has blink and dim
+# + in bce test, blue isn't really blue but some pale purple
+# + modified keys mostly work, but its tab control interferes with some
+# + rmm/smm don't work (always uses escape-prefix)
+# wraptest:
+# + poor (doesn't copy anyone, most of the results are wrong)
+# vttest:
+# + DA is VT5xx with sixel, selective erase, user windows, color
+# + DA2 is VT220 version 277
+# + only the VT100 character set works, contrary to DA/DA2.
+# + no NRCS, either
+# + double-sized character work, with some debris
+# + doesn't switch between 80/132 columns.
+# + numeric keypad ANSI application mode escapes don't work.
+# + numeric keypad ANSI mode misses "0", ".", ","
+# + uses PC-style editing keypad \E[H and \E[F for Find and Select
+# + no VT52
+# + DECSED selective erase doesn't work
+# + SRM doesn't work
+# + 8-bit controls don't work
+# + DECNCSM doesn't work
+# + most DECRQSS do not work (DECSCL, DECSTBM, DECSLRM respond)
+# + DECRQM/DECRPM don't work (most reply permanently reset)
+# + DECLRMM responds to DECRPM, but VT420 rectangle tests do not work.
+# Some of the left/right margin tests work with the cursor-movement screen,
+# but DECFI/DECBI do not work. The other cursor-movement tests are buggy.
+# + implements ECMA-48 cursor movement, but not SL/SR or protected area
+# + implements xterm normal, any-event and button-event mouse, none of the rest

+# + modified F1-F4 are wrong, sending SS3 with modifier numbers

+# + meta key doesn't work
+# + status-line works (based on xterm, including window-resizing)
+# + dots don't line up for home test

+#
+# vttest:

+# infocmp vs xterm-256color
+# + missing XM/xm
+# + rmcup/smcup doesn't use title-stack (but is implemented)
+# + doesn't use SGR mouse (but is implemented)
+# + sgr doesn't define dim, but dim capability is in terminfo (implemented)
