I'm trying to send data on my serial port through Simulink with the toolbox in description, but when i configure the Serial Configuration Block, it give me this error. I don't think the problem can be the port, because i have atteched an Arduino Uno.

What version of MATLAB are you using? Have you contacted support with your question?
I have the same problema. Do you got any real solution for this?

I have the same problem, i was using virtual ports to simulate what I wanted to do and it worked well... but when I conected the real serial port it just doesn't work

I also have the same problem trying to connect to a virtual port for Ti MSP430 launchpad.

For anyone reading this I used to have this same problem; however, I think I found the solution. Simply connect your hardware (Arduino) to the computer before opening Matlab. Then (with the hardware connected) open Matlab, then open your Simulink model and configure the Serial Configuration Block, it should work just fine now. After doing so, you can save your Simulink model and the serial configuration will be saved as well.

I had this problem, then ran Matlab in Administrator Mode, which fixed the issue.

Have you tried using the Arduino Serial Transmit instead of the Instrument Control Toolbox one? I think that will resolve this issue.

i have the same problem. In my case, it turns out it's the conflict between 2 serial ports ( i'm trying to open 2 serial port in the same simulink model) cause this error message.
