Olga Weis Jul 27, Advanced RS monitor software by Electronic Team. Serial Port Monitor. Download day fully-functional trial period. Some highlights are: The ability to open and monitor a port already opened by another application.

Four different data views. See your data in table, line, dump or terminal mode. You can also see all modes at the same time in the display window Flexible and user-friendly interface that allows easy access to your serial ports without the need for any programming skills. Playback and session comparison lets you repeat the exact commands or data sent to a device and automatically displays the differences between sessions.

Monitor multiple ports within one monitoring session. Send monitored data to files or the clipboard for easy analysis. Fully supports all Windows versions including Windows Free Serial Port Monitor Free Serial Port Monitor is a RS protocol analyzer that provides you with a simple and effective way to sniff the incoming data from both virtual and real serial ports.

No unnecessary costs: This software is totally free! Free Serial Protocol Analyzer by HDD Software Here is another free software tool that is designed to run on older versions of Windows and will allow you to display and analyze data exchanged between an application and a serial device. Portmon for Windows Portmon for Windows lets you monitor and display both serial and parallel port activity on legacy versions of the Windows OS.

Top hardware solutions for RS monitoring RS monitor hardware was purposely designed for engineers to detect and resolve emerging network issues. Main benefits of using Versa Tap for serial data capturing are: High usability: Hassle-free and quick hardware installation thanks to the screw-terminal communication interface connection. The set-up process is pretty much straightforward. Run the IO Ninja app and select your sniffer on the list. Define the baud rate of the serial communication you want to monitor.

How can RS Protocol Analyzer help developers perform tasks? Among them are: A serial monitor lets you monitor multiple serial ports at the same time Use of an serial monitor allows you to evaluate multiple serial ports simultaneously. A COM monitor means you do not need to use extra cabling Using an RS monitoring software application removes the requirement for extensive cabling to be employed. Latency and time-tagging issues can be minimized with a serial monitor Time-lag issues and latency are minimized with a serial port monitor.

A COM monitor can be used by anyone. All codes have been tested on a 64bit Windows 10 System. All the codes in this tutorial are licensed under MIT License making it eligible to be used for developing proprietary software applications. These high voltage transients can cause severe damage to your computer or its ports. It is highly recommended to use an. Compilers and IDE's used. Since we are developing on Windows platform,.

In Visual Studio ,there is no longer an option for creating a C project. C extension Eg: MySourceFile. Compiler would automatically do the rest. The Code uses some Microsoft specific safe C functions like.

The code will compile on GCC after removing those functions. Make sure that variables referenced by those functions are also changed. Finding out your COM port Number. A little bit of History,. Serial ports are simple 9 pin legacy ports used by the PC to communicate with external peripherals like Printers,Data Acquisition Sytems,Printers etc.

The simple protocol and the 3 pin hardware physical lines RX,TX,GND made it quite popular among manufacturers who wanted an easy way to connect their devices with a computer. The once ubiquitous serial port have been completely replaced by the familiar USB standard. These chips provide a virtual serial port that behaves like a real one but transmits the data through USB.

In Windows ,. To find out the COM number corresponding to your serial port,. If you double click on COM24,you can see the details of the corresponding port. Windows10 Accounts. Opening and Closing a Serial Port. CreateFile is a Win 32 function which is used to create or open a file, stream or an IO device like serial port. On success CreateFileA will return a handle which is then used to refer the connection in all subsequent operations.

After opening a serial port using the CreateFileA function you should close it with CloseHandle function, otherwise port will become unavailable to other programs. Now let's write a small program to open and close a serial port on Windows.

To Configure the DCB structure we use two functions, GetCommState function which retrieves the current control settings of the serial port and SetCommState function which configures the serial port with the new values in DCB structure provided by us. Changes the language of AccessPort. The "Monitor" category has functions to control the Monitor mode. The "Tools" category is a collection of some useful software tools.

Transfers a file. Select the file you want to transfer and press the "SEND" button. Configures the COM port and serial settings. The default view is the "General" configuration menu option. The "General" configuration menu option contains the main serial port settings and configuration. The "Custom Baud Rate" selects the baud rate data is being transmitted and received. The baud rate is the speed in which the data is be transmitted.

The supported baud rates range from bps to , bps. Standard baud rates are available from the dropdown menu in the Serial Port Settings section. Custom baud rates can be also entered by checking the "Enable" option and typing the custom baud rate. The "AutoSend" allows the output data to be continuously transmitted with a delay in ms at the end of each transmit specified by the Cycle value.

The "Advanced" can automatically open a port as soon as the application starts, or notify of any available updates. Check the "Event Control Settings" options you want to trigger an event.

The "Flow Control" settings can be used if flow control is necessary. Flow control is not used by default. Input and Output timeout control settings are configured here using the "Read Timeout" settings and "Write Timeout" settings.

This is an advanced feature that will not be covered in the document. The dropdown looks like this. The "Operation" category is a collection of operational functions. The bottom status bar displays the TX count and RX count.

These counts represent the number of bytes transmitted and received. Reset Counter resets these counts to zero. The "Help" category is a collection of help related operations.

Returns relevant information regarding AccessPort. The version and build numbers can be obtained from this page. The input display box is where the data that is received by AccessPort is displayed. On top of the input display box is an icon toolbar with common data input functions. The output input box is where the data to be transmitted is typed in. The toolbar on topallows you to input data in Hex or Char format, plain text or hex string format and in real time or not.

The bottom status bar shows the handshaking and flow control indicators of the comm status. It also show the TX transmit and RX receive data counts and serial port settings. Two application examples will be presented demonstrating how AccessPort can be used to test our products. The first application is a simple loopback test of a single serial port or serial device.

The second application demonstrates the data communication between two serial ports or serial devices. In both examples the terminal modes will be used.

A single port or device loopback test is a very useful way of determining whether a serial port, attached device, or converter is functioning properly. A loopback test can only be performed on other full duplex simultaneous bidirectional serial devices protocols. Our fiber optic converters can be looped back by connecting fiber in to fiber out. RS is half duplex and cannot be single converter loop back tested.
