Handshaking is also called "Flow Control". The main purpose of Handshaking is to prevent receiver overloading. By using Handshaking signals, receivers will be able to tell the sending device to pause data transmission if the receiver is overloaded. There are three types of handshaking: Software handshaking, Hardware handshaking and Both. The receiver sends these control characters to pause transmitter during communication.

The drawback of Software handshaking is that these two control characters can not be used in data. This is quite important when you are transmitting Binary data as you might need to use these two codes in your data. DCD Data Carrier Ready is used by the modem when a connection has been established with remote equipment, while RI Ring Indicator is used by the modem to indicate a ring signal from telephone line.

Binary is the Base-2 numbering system. One byte of data consists of 8 binary digits, from to Hexadecimal is the base system, which consists of 16 numbers: 0 to 9 and the letters A to F decimal number The Hexadecimal numbering system is useful because it can represent every byte as two consecutive hexadecimal digits, and it is easier for humans to read Hexadecimal numbers than Binary numbers.

Most of the manufacturers use Hexadecimal in their protocol documentation. It is simple to convert a value from Hexadecimal to Binary. Just translate each Hexadecimal digit into its 4-bit binary equivalent. Hexadecimal number F3 equals Binary number Decimal refers to numbers in base 10, which is the numbering system we use most in everyday life. It's not as easy as Hexadecimal and Octal to converter Decimal to Binary number, but it is easier for us to understand Decimal.

Octal refers to the base-8 numbering system, which uses just eight unique symbols 0 to 7. Programmers often use Octal format because it is relatively easy for people to read and can easily be translated into binary format: each Octal digit represents 3 binary digits. Octal number 73 equals to Binary number ASCII codes both readable and unreadable are widely used in communications, such as Modem communications.

Many serial protocols use checksum additional bytes added at the end of the data string to check the data integrity, as errors might occur during data transmission.

Using Modula as an example, we learn that before data transmission, the sender adds all command bytes together then mod it by decimal to get an additional byte. This is to be added at the end of the command string. When the receiver receives the command string, it will first check the added byte to see whether data remain unchanged or not. If that is the case, it will accept the data, and if not, it will ask the sender to resend the data.

A protocol command is a data string sent from one serial device e. For a more detailed video demonstration on configuring and using WinWedge, watch our "Start Here" Tutorial. Connect your device to your PC's serial or USB port installing any necessary drivers and use the WinWedge interface to select your device's communications settings, such as the COM port, baud rate, parity, data bits, and stop bits. Intuitive, walk-through menus allow you to tailor the data to your needs by splitting the record into multiple fields, filter out certain characters, or format the data to meet your requirements.

You can also easily define hot keys and buttons to send serial commands to your device or perform other tasks. You can even input the device data directly to a chart or use Excel's built-in functions to peform real-time analysis. Great Program! Your company TALtech is by far the most responsive company I've come across on the internet.

Thank you! It is a small software package that will not take up any significant resources on your computer. 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.

It was developed by professionals experienced in serial device architecture and can be a powerful tool for development, debugging, and optimizing serial applications. One drawback to this software package is that it does not support the newer versions of the Windows OS. This makes the tool less useful than others that support Windows It is worth a look if you are using Windows , Vista, or other older Windows versions.

Portmon for Windows lets you monitor and display both serial and parallel port activity on legacy versions of the Windows OS. The package has a number of useful features that increase its utility for serial device or application developers. The tool supports remote monitoring across the network and lets you capture your monitoring sessions to a file for later analysis.

This tool will help you understand how RS serial communication works with its advanced filtering and search capabilities. You can copy a line from your output window to the clipboard for use in other programs and can set highlight colors for a more user-friendly display. RS monitor hardware was purposely designed for engineers to detect and resolve emerging network issues.

Versa-Tap is well-liked amongst many professional engineers for its unmatched data-logging and analyzing capacity. Serial Tap is a simple and effective hardware tool intended for use together with the IO Ninja software app. Without the use of an RS monitoring tool, it is difficult to check the data flow between a serial port and a computer. By employing such a tool, the user can easily display, log, monitor, and analyze the serial port activity of their system.

There are a number of ways that an RS port monitor can assist developers and make their jobs easier. Among them are:. Use of an serial monitor allows you to evaluate multiple serial ports simultaneously. This ability lets you see your system in its entirety at one time rather than having to test each port or device individually.

This can save time and give you a better picture of your overall system performance as it relates to serial devices. Using an RS monitoring software application removes the requirement for extensive cabling to be employed. This can save money as well as reducing clutter in your office. Usually, if you are using RS monitoring hardware you will need expensive cables that will quickly become a nightmare to manage.

Saving on the expense and hassle of cabling is an excellent reason for using a software solution like Serial Port Monitor by Electronic Team, Inc. Time-lag issues and latency are minimized with a serial port monitor.

Traditional COM port monitoring solutions often leave developers experiencing latency and time-lagging issues that make their monitoring tasks more difficult. A quality serial monitor can help eliminate these issues by presenting the monitoring information in a user-friendly manner and allowing the user to save monitoring data to a file.

Time-stamping of data transmission and handshaking events make it easy to analyze your monitoring results at your convenience. COM monitors typically require no programming skills to be used effectively. Installation is usually straightforward and can be done by anyone with basic computer skills.
