ABSTRACT:
A wireless communication apparatus in which a main unit transmits an external-line status message corresponding to status of an external line, to a portable telephone via a connection unit when the status has changed. The portable telephone indicates the status of the external line by an external-line LED if the telephone is in an indication mode, based on the received external-line status message. However, if the telephone is in a no-indication mode, the telephone stores the received external-line status message into a RAM. Thereafter, if the no-indication mode has changed to the indication mode, the telephone displays the status of the external line by the external-line LED, based on the stored external-line status message.
