Dear Walter Roberson, thank you for your answer. I found the question is that each 8-bits data has a start bit and stop bit as you said. So if there are some ways to remove the start bit and stop bit to make the signal continuous? Thank you very much!

When you are measuring the wire signal levels of RS232, then the Start and Stop bits are unavoidable.
Side note: the Start bit is a different length than the Stop bit. I seem to recall that the Stop bit is half of the length of other bits.

Hi,
It seems like sending deimal values inside the function would help in this case.
Please use the code as below:
write(app.SerialObject, [85, 86, 87, 88], "uint8"); % Decimal equivalents of binary numbers
Refer to 'write' function documentation below for further reference:

I hope this helps!
