ascii character problem

[Gale Johnson]

I am trying to send information via a serial port to an electronic machine. The machine requires a coding of "K" to start, followed by CHR(02). At the end of machine coding I need to send CHR(03). Instead, the characters being sent are chr(191) and chr(192). Is there some way to force the serial program to send the correct 02 & 03 ASCII characters?

You should use Serial.Output2 to send the required bytes.
The Bitwise library allows you to convert strings to bytes and vice versa.
