![]() ![]() ![]() ![]() In the older versions of Windows, there was a terminal application included but it has been discontinued. But even then we need a terminal software so that we can actually send and receive commands to the serial communications port. Some of the electronic boards have four pins indicating VCC, RX, TX and GND while others just leave it to the user to solder the wiring on the labeled points.įor such a four-pin interface, we need a special device called USB-to-TTL adapter which is easily available from any online shopping site such as Amazon or eBay. But inside the router, there is usually a low level communication port which is done through a UART (universal asynchronous receiver & transmitter) pinout. For example, a typical WiFi router has USB port, an Ethernet port and maybe the RJ25 port for the ADSL variants. Advanced electronic devices offer more than one way to communicate with them. ![]()
