Hi to everyone. I must develop an URCAP which use the serial communication on the E - series. I also see that this is possible with a daemon which can manage the serial communication. My question is : can i test the serial communication on the emulator or it’s possible only on a real robot?  
Thanks to everyone !!!

Hello there, I am having the same issue to try an URCAP in URsim, did you solve it?

Thanks for your time.
