NAME

Tty - set/print Tty variables

SYNOPSIS

WA2LWinTools/lib/shell/Tty [ -h | -V ]

Tty ( -p | -r )

AVAILABILITY

WA2L/WinTools

DESCRIPTION

set/print/reset environment variables in the terminal (Tty).

The Tty command is started on wtshell initialization.

Because the console (1m) command and the Windows™ cmd.exe shell handle no singnals on resize, the Tty command can be used to update dynamic variables (like %COLUMNS% and %ROWS%) manually.
