value defines the range of legal ASCII input values. Any character received that falls outside of this range will not be accepted into the input field, but may define other actions such as field editing or input termination. Two decimal numbers, separated by a comma, express the lower and upper bounds of the range. The maximum range is 1,255. The default range is 32,255. This value may also be set using the configuration variables KBD_DATA_RANGE_HIGH and KBD_DATA_RANGE_LOW.

If the same number(s) is included in both the DATA-RANGE and EXCEPTION-RANGE, then DATA-RANGE takes precedence.
