You can test it if you run 2x Hercules SETUP as the TCP client in first window and TCP server in second window.It was created for HW group internal use only, but today its includes many functions in one utility and its Freeware With our original devices (SerialEthernet Converter, RS-232Ethernet Buffer or IO Controller) it can be used for the UDP Config.
Rs232 Serial Port Monitor Serial Port LinesYou can check and control all serial port lines (CTS, RTS, DTR, DSR, RI, CD). In this window you can assign the IP address to compatible devices ( PortBox, PortStore, PortStore2, IO Controller, Charon 1 module, Poseidon etc. Clicking on a particular MAC address will highlight it and will show the parameter values of the respective device in the Required parameters field. For the Connect with TCP Client button to work it has to be set to 23 (Telnet). This value must result from multiplying the remote IP address and the restriction mask (option N), otherwise the device does not react. More details to the IP Filter you can find in the devices manuals, include examples and counting formulas. Security can be greatly enhanced by setting a fixed address or a suitable restrictive mask that disallow communication with unauthorized parties. IP requesting access AND N ) W If this condition is valid, you can access the device (AND is binary multiplication). In the TCP Client menu you will see the device configuration mode. If the Port field of the device (the port where the device listens to) is not set to 23 this connection will fail. When a receiver is ready for data, it asserts the RTS line indicating it is ready to receive data. ![]() The flow control used to protect against data overruns, uses data bytes as control characters. XONXOFF protocol is controlled by the data recipient who sends an XOFF character (ASCII DC3, decimal 19, hex 13) to the sender if it is unable to continue to receive data. The sender suspends transmission until it receives an XON character (ASCII DC1, decimal 17, hex 11). ![]() The ASCII characters are sent by typing xxx (where x is a number in 0.9), yy (where y is a hex number) or for example for line feed or for carriage return. Its defined in most of our devices as 4 groups with 4 bytes defined in HEX form. If your TEA Key is equal to the Key on the opposite side, the TCP connection is enabled. Otherwise the connection is with some timeout closed by the TCP Client (device). Its function dedicated for the PortStore and PortStore2 testing. ![]()
