void loop() {
 recvOneChar();
 showNewData();
}

void recvOneChar() {
 if (Serial.available() > 0) {
 receivedChar = Serial.read();
 newData = true;
 }
}

void showNewData() {
 if (newData == true) {
 Serial.write (receivedChar);
 newData = false;
 }
}

reduces to:

void loop() {
 if (Serial.available() > 0) {
 receivedChar = Serial.read();
 Serial.write (receivedChar);
 }
}
