What is ReadTimeout good for in serial ports?

[Ole]

I can't get the sense of the ReadTimeout property in the serial port - what
is the function of it? the serialport.Read returns immediately no matter how
many bytes you ask it to read and no matter what ReadTimeout is set to????

Thanks
Ole

Ole,

Why not post a code sample and detail what you are trying to do. It's a
little hard to tell what it is doing without seeing what you are doing.
