Abstract
A text message originated ringer operates to carry out some operation based on an embedded control code in the message. The message includes all text, but some of the text characters are reserved. A control sequence, also in text, is contained between two reserved text characters. That control sequence is used to control the ringer in the remote phone. The control sequence is not displayed as part of the text message, but instead is only used as the control.
