Our serial port data capturing software has been developed and constantly improved for more than 20 years. This is entirely a software COM port analyzing and serial port data logging solution that allows you to avoid using hardware equipment, null-modem cable, additional DB-25 or DB-9 connectors and so on. In addition to visualizers, product includes tools for data exporting, reproducing data from previously recorded log files, redirecting this data to COM ports, advanced serial port terminal, utility for sending MODBUS Commands and built-in scripting for tools automation. Serial Monitor provides not only a wide range of visualization tools for popular serial protocols (including PPP, MODBUS, BACnet MSTP) and raw data, but also utilities for creating your own custom visualizers, allowing you to parse any data and custom protocols in a convenient way. The application's various editions include features for filtering, browsing, searching, recording, and data playback. It has full set of tools for successful decoding of serial protocols and analyzing packets data. The program facilitates the development, debugging and analysis of software and hardware solutions that use serial communications for data exchange. This software allows you to monitor the data that devices and apps exchange over serial ports. NOTE: The modem may not always give a dial tone with this test procedure because a number does not follow the command however, the modem should give some kind of signal that information was received.Non-intrusive software serial port sniffer & RS232/RS422/RS485 protocol analyzer for Windows. The first command, Attention, signals to the modem that it is about to receive information, and the Dial Tone command instructs the modem to enable a line to dial out. The ATDT command is a signal to the modem that is interpreted as Attention Dial Tone. The modem should respond with a dial-tone or just a communication signal. Where X is the number of the serial port the modem is connected to or emulating. If an MS-DOS-based application cannot be used, it is possible to test the modem connections by typing the following command at the MS-DOS command prompt When you troubleshoot communications problems in Windows, an MS-DOS-level communications program is often required to test the modem and ports outside of Windows.
