Hi, I am using serial port communication. I can write and read the data but the warning after "fscanf" keep pop up. Below attached the code. Code:
s=serial('COM6','BaudRate',115200,'Parity','none'...
,'DataBits',8,'FlowControl','none'...
,'Terminator','LF/CR');
fopen(s);
fprintf(s,'t');
out = fscanf(s)
Warning: A timeout occurred before the Terminator was reached.
May i know what is the problem?

I am also having the same problem even after using the code
set(s, 'TimeOut', 100)
can you help to get rid of this?

Check the baud rate you are configuring.
Check that the terminator matches.
Use a program such as TeraTerm to verify that you are able to receive data from the port.

If the timeout occurred to early, what about increasing the time?
set(s, 'TimeOut', 100)
? But the default of 10 seconds should be long enough... Perhaps the other parameters are not correct?
