![]() No additional handshaking is used for network implementations beyond that provided by TCP/IP. Hardware handshaking (DTR/DSR) is not implemented. Software handshaking (XON/XOFF) is implemented in some types of marking systems to control the flow of information. Serial implementations often use a form of handshaking to control the flow of data. When implemented via an RS232 serial connection, the port is opened with the following parameters: When communicating over a network, the Extended Protocol is typically implemented as a layer above TCP/IP. This document is correct to the best knowledge of InfoSight Corporation which reserves the right to change the document's contents or the systems referred to at any time without prior notification.Įxtended Protocol can be implemented over legacy serial RS232 communications ports as well as more modern networking technology such as Ethernet. This document assumes familiarity with the ASCII character code as well as fundamental computer programming skills. ![]() Extended Protocol is intended to provide secure communications with an intelligent host device. This document will describe the Extended Communications Protocol as implemented with InfoSight Marking System software.
