<p>PROBLEM TO BE SOLVED: To provide a communication system in which an e-mail received from a master set can be transferred to a slave set and the e-mail can be transmitted from the slave set. SOLUTION: When receiving an e-mail, the master set checks whether or not it is set to the transfer mode to a slave. When the master set is not in a salve set transfer mode, the e-mail is received by the master set similarly to a conversional case. When the master set is set in a slave set transfer mode ('YES' in S201), it is checked whether or not the slave set is in a state that the e-mail can be transferred (S204), and when the slave set is in a state that the e-mail can be transferred ('NO' in S204), the e-mail is received by the master set to be transferred to the slave set (S208). For example, if the slave set is in the state that it is not ready to receive the e-mail in such a case that the slave set has a low remaining memory size ('YES' in S204), the master set does not receive the e-mail.</p> |
