Visual Basic 2010 - Send ASCII over Serial port not the same as Displayed in programm

Question

I want to send the ASCII code 241 which is a "ñ" over the serial port. However at the other end of the Port I always get a "?" instead of an "ñ". Why is the character changed?

MessageBox.Show(Chr(241))          'gives "ñ"
SerialPort1.Write(Chr(241))        'gives "?"

Answer 1

So i found the Problem I just added now: SerialPort1.Encoding = System.Text.Encoding.GetEncoding(1252) and it works.

Thx anyway for all the help

Answer 2

there is extended ascii, but your character would be 164, not 241. http://www.asciitable.com/ You have to find out what your device supports.

char 241: http://www.theasciicode.com.ar/extended-ascii-code/plus-minus-sign-ascii-code-241.html

char 164: http://www.theasciicode.com.ar/extended-ascii-code/spanish-enye-lowercase-letter-n-tilde-enie-ascii-code-164.html
