Forum Post: Managed Code Encoding Serial Port

Hi Community! I have encountered a problem sending data past x"3F" over a serial port in managed code. In the docs I read you need to set the encoding to go past the 7-Bit(??) limit. So I did the following: set serialPort1::Encoding to type System.Text.Encoding::GetEncoding(737) * tried other values like 1252 as suggested in different forums. But when I do: invoke serialPort1::Write(x"FF") * it results in 3F being sent. where is Bit 8? Somehow I don't get the catch. Should be simple though. I hope someone has an answer. Regards Rainer
