2 serial monitors cascade window in one PC for nRF24L01+ string RX-TX

Hello everybody,

I want to demonstrate the nRF24L01+ example. - YouTube
I have uploaded the sketches to 2 different arduino boards (UNO, Duemilinove). Unlike the video, I cannot open 2 serial monitor simultaneously. The 2 ports are PORT 11 (TX sketch )& 12 (RX Sketch) in my case. when I try to open serial monitor for 2nd device , it closes the previous one. Cannot view the two different serial monitors at the same time. Can you kindly provide a quick tweak to solve this issue.???
Thanks a lot for your time to consider my issue.

Good day.

Download a standalone terminal such as TeraTerm and connect to the other unit thst way.

thanks for the quick tweak. I still wonder how the uploader manage to view 2 serial monitor simultaneously!
Thanks again for your help...

You can open two (or more) COM ports using the Arduino IDE by launching separate instances of the IDE.

I've run a mega and an arduino at the same time. I Just opened a second instance of the IDE and selected the second available comport.

Thanks PeterH, zoomkat for the solution. Two serial monitors are opened as I wanted. The sketch is behaving in a weird way. After uploading the TX & RX sketches, both the PIN13 LED should glow but the LED of TX board is now glowing in none of the UNO boards (I burnt the UNO bootloader in my dueminilove board, I think I have 2 UNO boards now.)
I have made all the connections as described (Image included) & double checked them. when I open & type something from the TX serial monitor, nothing appears in the RX serial monitor. The library & examples are attached herewith the post.

If it seems to be behaving strangely I suggest you do a sanity check of the hardware by uploading a sketch that just writes a fixed message to the serial port to confirm you are successfully uploading the sketch and have basic serial I/O working. Once you know that, you can use serial trace messages to work out what is happening inside your transmitter and receiver sketches.

Thanks for your interest & help. I will do as you suggested. Lets see what happens!
