I want to read a single character from the RS232 port to turn on or off debug / interest features in my program. Here's the code I am using: if (Serial.available() > 0) { // read the incoming byte: int incomingByte = Serial.read(); if (incomingByte == 83) // "S" …

Reading RS232, buffers, line feeds etc

Are you saying it is THAT that holds the data in a buffer and doesn't send it until you press enter?

Yes.

Any way around that?

Sure. Don't use the Serial Monitor.
