Abstract
A modem parameter required for a modem apparatus is stored in a memory for each telephone number of a communication destination in advance based on past communications. At a communication time, a receiver side is notified of an execution of the short protocol by a QTSD signal, and sequentially a QINFO signal that includes the modem parameter is transmitted. Since the modem parameter is received by the communication destination, the pre-protocols such as exchange of parameter, etc., are shortened so that communication time can be shortened. Moreover, since the transmission of modem parameter is repeated until it is confirmed that the communication destination receives the modem parameter, occurrence of communication errors can be avoided so that the shortened pre-protocols can be surely executed.
