<p>In order to record a message receipt time and at the same time ascertain a message recall, the receipt of a ID address code is determined and the time at which the ID address code is received is set as a new receive time. The new message which follows the ID address code is compared with a message previously stored in a memory and, the new message and new receive time are set in memory in the event that the new message and the previously stored one are not the same. On the other hand, in the event that the two messages are found to match, the receive time at which the old message stored in memory was received is replaced with the new receive time. Alternatively, both the new and old receive times are be stored and displayed. <IMAGE></p> |
