space
The light element of a printed bar code symbol. The white lines.

provide initial timing references and direction of read information to the
coding logic. For HIBC purposes, the asterisk (*) is used.

timeout
An error recovery rule. The amount of time the controller or the polled device

enabled, the timeout event must be disabled entirely. To enable flow control,
define XON to be other than NULL.
