Abstract

PURPOSE:To avoid the waiting time required for steps, by transmitting a packet indicating affirmative response and reception disable continuously when a start request is received at disabled communication, and transmitting a packet indicating reception enabled when the communication is made possible. CONSTITUTION:When a data terminal DTE(A) transmits a start request(RI) at disable communcation of a data terminal DTE(B), the DTE(B) returns a final response (RF) being an affirmative response. In this case, the DTE(A) judges the start of job and transmits the data DT packet. A RNR packet indicating disable reception is transmitted from the DTE(B) to suppress the data DT transmission from the DTE(A). Thereafter, when the DTE(B) is possible for communication, the RR packet indicating reception enabled is transmitted.
