Coolterm

Exchange text and other data between connected serial ports

Open and CoolTerm 5. Connect to your serial port should look something like COM3 or USB 1121. Set the baudrate to 115200. Select the Terminal tab and make sure your the line Mode option is selected under Terminal mode. CoolTerm is a great tool to have around if you need to control hardware devices, such as robotic kits, micro controllers, servo controllers, and so on. The application can connect to various ports, enables you to send text commands, and then displays the data received from the hardware device in HEX or ASCII mode. CoolTerm is a very popular cross-platform serial console application developed by Roger Meier. It's got all the necessary features for communicating with hardware devices and an elegant user interface. One awesome feature of CoolTerm is Hex View. If you want to see the actual hex values of the data you are sending rather than the ASCII values, Hex View is a tremendous help. Click the View Hex icon. The terminal’s appearance will change slightly. Now whatever you type will show up as hex and ASCII. The first column.


CoolTerm was developed as a useful and user-friendly software and acts as a serial port terminal application.

CoolTerm is a tool that's geared towards hobbyists and professionals with a need to exchange data with hardware connected to serial ports such as servo controllers, robotic kits, GPS receivers, microcontrollers etc.

About Me

Coolterm

My name is Roger Meier, and I am NOT a professional programmer. Writing my own programs is a hobby that I picked up when I couldn't find any decent (if at all) freeware or shareware for certain tasks for which I wanted to use a computer.
I picked Xojo (formerly REALBasic) as my language of choice for several reaons, including its structure, its 'object-orientedness', its capability to create executables for Mac OS X, Windows, and Linux Platforms, and last but not least for its fairly large and helpful user community.
Over the years I've created a fair amount of small apps and tools for my self, and every once in while I end up with something that may be of general use. These are the applications that are posted on this website.
If you are a Xojo programmer or hobbyist like myself, I also host several open-source projects that you might be interested in.
