Several years ago, computers' serial ports used to be very helpful for establishing communication between the computer and numerous external devices of various types. Even though those ports have gradually been replaced by the USB technology, serial ports are still available on most modern PCs. Free Serial Port Terminal provides you with a visual means of sending and receiving data through your serial ports.
The program opens a light and easy-to-use interface with all the necessary elements for you to establish and monitor the communication. The program lets you choose what port you want to monitor, allowing you to open and close it manually. It also includes a big box where all the transmit/receive data and all the messages are displayed with the same look and feel of Microsoft Windows HyperTerminal utility. Thus, you can fully control all the information transmitted and received to and from your external serial device. It also offers you controls for refreshing that information and for clearing the box, as well as the option of enabling and/or disabling the auto-scroll function for that box.
The program also offers you a special feature - you can add those commands you usually need to transmit through the port as toolbar buttons. They will allow you to save a lot of time in the future. At the bottom of the interface, there is also a drop-down box where you can type and send commands. It stores the last few you wrote, making them easily accessible. Finally, it also shows virtual LEDs, which will blink as data is being sent or received. more
