ABSTRACT:
A local network system interconnects computer devices, such as cash registers, scattered in a relatively small area. The local network system includes reception control element for determining the packet format of data received from a data transmission line and forming a response packet based on the result of the determination; a transmission control element for delivering data that is to be transmitted, or the response packet, in a prescribed packet format over the transmission line, and transmission and reception control elements for controlling the transfer of transmitted and received data between the reception and transmission control elements and terminal devices. Access to the transmission line, generation of packets, data buffering, retransmission control and other operations are effected not at high level or an application program level, but at the level of an interface or data transfer control apparatus that interconnects the terminal device serving as a main system.
