Appendix B. Break/Address Timing

A BREAK consists of continuous spacing for time greater than 10 times the

inverse of BR (baud rate). The BREAK is followed by a marking period and

single byte ADDRESS. The marking time must be greater than one times the

inverse of BR and the marking time and ADDRESS must be completed within

100 msec.

This is to say that a 9600 baud, the BREAK must be greater than 1.1 m sec

followed by marking for 105 usec. The 8 bit single character ADDRESS (least

significant bit first) is then completed within 100 msec after the end of

BREAK.
