Virtual terminal not showing in Proteus?? No problem here is the solution for that. Many of you are facing the problem that when you run the serial monitor or output from the oscilloscope is not showing. The same was with me, then I have read many articles on the internet but didn’t find any reasonable answer. After so many tries I was able to solve this issue and have decided to share this with you.

A Virtual Terminal is an important tool in Proteus and helps a lot while performing simulation on the serial modules like GSM, GPS, XBee, etc. So while using this tool if you are stuck and unable to get it back. I can guarantee that after reading this article you will be able to solve the serious issue. Also, it will save you precious time.

What is a Virtual Terminal? 

Virtual Terminal is used to communicate with the microcontrollers in Proteus. This will help your circuit in testing before implementing the hardware. So you can easily test and implement the circuit with the help of Proteus software. If the results are satisfactory you can easily implement the hardware.
