The Virtual Terminal looks like the one in the following image: The Virtual Terminal in the Proteus is bi-directional which means that it can send and receive data simultaneously.Thus the Virtual Terminal plays the role while simulating the embedded systems that compliance the serial communication through the Universal Asynchronous Receiver or Transmitter. It should have come in the reader’s mind that how we can see the data transmitted to or from the microcontroller serial port in the software.So while writing the code for serial transmission and designing the circuit it is required that the code and design should be tested for serial communication, so that any problem in the code or communication can be resolved before implementing the circuit physically.
With the help of Virtual Terminal one can easily simulate the serial communication that he / she use in his / her embedded systems.
Virtual Terminal is a very useful tool available in the Proteus.
