Is it possible to run HTem and Arduino Serial Monitor in parallel

Hello Friends,

I am using Arduino Mega, I want to have two way communication with sensors. My idea is that i will send the commands and data through Hterm and ardunio will recive it and afterwards Arduino will send the data to Serial monitor.

I tried it but not working. I believe both are using same COM Port 3.

That's more a question for a Windows forum: "Is there a way two programs concurrently accesses one COM port?".

I don't see any reason to do this by the way. Please specify which functionality of the Serial Monitor you're missing in you "Hterm" (you forgot the link) and vice-versa.
