[!NOTE] Plan 9 is supported on a best-effort basis, as the main Tcell development team does not have a Plan 9 environment.
The Plan 9 backend opens /dev/cons for I/O, enables raw mode by writing rawon/rawoff to /dev/consctl.
It watches /dev/wctl for resize notifications.
The default mode for vt((1) is VT100, which will only provide basic monochrome text, and few additional features.
In this case, it is expected that TERM=vt100 is set.
It may be possible to emulate more modern terminals using -2 (VT220), -a (ANSI), or -x (XTerm) flags to vt.
While this has not been tested, the use of -x to get xterm like features, combinerd with a TERM=xterm may yield superior results,
including possibly color and mouse support.
Note that if Tcell does not find a suitable value for TERM in the environment, it will assume XTerm like functionality.
