Timing Diagrams | Apollo IMY instruction

If illegal commands or characters are sent to the IM, an asterisk (*) must be sent to clear the input buffer. The IM will not respond to an illegal or incomplete transmission. The diagrams show the difference in the timing considerations for either Abbreviated or Full Character Transmission, or if a Reset Command is issued.
