Computers come with many different types of easily accessible external ports such as parallel ports, serial ports, USB ports, PS/2 ports, Ethernet ports, HDMI ports, etc. These ports are used to connect to other devices through a compatible cable. Depending on the type of devices and the ports available on it, we can use one or more of these ports for communicating with that device. For example, if you want to flash a new firmware on a soft-bricked router, then you might want to use the serial ports. Raspberry PI and Arduino boards also offer serial communication.
But the cables and ports are not enough for the communication to take place. You also need a serial communication software such as SerialTool. It is an advanced software that covers all the basics of the serial devices communications.
Before we start using the SerialTool, we need to find out which of the serial ports are available on our computer. We can find them easily from the Device Manager on Windows (using the command control devmgmt.msc) listed under the “Ports” category.
In the SerialTool, we have to go to the settings section and add the available ports and assign it for use. Without taking this step, it won’t be able to access the serial ports even if they are available on your PC.
Once the ports are all setup, we can start using them for communication with any of the devices that are connected to your serial port. If you do not have a device, you can test your setup by using the loopback test in which Rx and Tx points are connected together.
SerialTool offers many advanced features such as comprehensive traffic response recording, automatic answer, scheduled sending, sending of files over serial ports in smaller chunks, alternating the data in hexadecimal or ASCII bytes and more.
