Hi

why is this piece of code not working?????
It's getting really frustrating.
I can not figure it out.

If I replace the readline method for readchar it's working. But one
character. I want to read everything from the serialport

SerialPort1.Open()

TextBox1.Text = SerialPort1.ReadLine

SerialPort1.Close()

I hope someone has the answer

How is the system suppose to know when "everything" has be read.

do a loop and use readchar

Did you see my reply to your previous inquiry?

Do you know that this "should" work? Have you examined the data from your
device to make sure that it actually it terminated with both carriage return
and line feed characters in that order?

There are other (better, IMO) ways to handle this problem.
