Defines a character string that will be output to switch the terminal from
132-column mode to 80-column mode.
Within the string, the sequence
\E is translated to the ASCII
ESC character (U+001B).
When the 3270 model is 5, and this resource and the altScreen resource are defined, c3270 will automatically send this string to change the terminal size when the host switches from the alternate (27x132) screen to the default (24x80) screen.
