$DEVICE

1995 Version of ANSI (Equivalent to Current ISO Version) of Standard

$Device reflects the status of the current device. If the status of the device does not reflect any error-condition, the value of $Device, when interpreted as a truth-value, will be 0 (false). If the status of the device would reflect any error-condition, the value of $Device, when interpreted as a truth-value, will be 1 (true).

$Device will give status code and meaning in one access. Its value is one of

where M is an MDC defined value , I is an implementor defined value and T is explanatory text.

The value of M, when interpreted as a truth value, will be equal to 0 (zero) when no significant change of status is being reported. Any nonzero value indicates a significant change of status.

The value of I is an implementation-specific value for the relevant status-information.

The value of T is implementation specific.

Note: Since M, I, and T are separated by commas, the values of M and I cannot contain this character.
