Serial port encoding

[Jack Russell]

I am trying to use the serial port control to send and receive 8 bit
characters to/ from a n instrument. whatever I set encoding to it
converts the characters.

Any ideas how to stop it?

Thanks

Can you give an example of the sent/received data? How did you find out that
it gets converted? How do you send the data (code)?

Sorry, I am not sending "strings" I am sending binary data.

You wrote:

serialport1.wri te(String)


I thought String means String. Now you write, you don't send a String.
What's right now?

This is the point, I and a lot of other people use serial ports to
transmit binary data, we do not want any encoding. According to the help
files the default is 7 bit ascii, but you can set the various unicode
alternatives. The help file says that setting 0 gives the "default"
which is patently not true

The solution is very simple. If you want to send binary data, send
binary data. Don't send it as a string, send it as a byte array.

Thanks, just what I wanted. I should have fully read the help file I
suppose, too many years of fooling devices so it never occurred to me it
would be that easy!

Thanks again
