Download our free serial port tester tool!
This Windows app is really handy when developing software which uses a serial UART port and was written by us as we couldn't find the perfect tool for our needs.
Select the COM port you wish to use and the port setup. Received data is displayed in in a wide horizontal window and also as a linear list of hexadecimal, decimal and ASCII byte value in a vertical window. You can create multiple transmit packets of ASCII text or byte values and also save your setup for future use.
