Let's try this then...

boolean sendSerial(long data, byte attempts) {
  byte Iattempts = attempts;
  Serial.begin(9600);
  Serial.print(data);
  while (Serial.read() != "*") {
    unsigned long startTime1 = millis();
    if (millis - startTime = 5000) {
      Serial.print("!");
      Iattempts =- 1;
    }
    if (Iattempts = 0) {
      return 0;
    }
  }
  Serial.print("+");
  while (Serial.read() != "^") {
    startTime1 = millis();
    if (millis - startTime = 5000) {
      Serial.print("!");
      Iattempts =- 1;
    }
    if (Iattempts = 0) {
      return 0;
    }
  }
  delay(5);
  return 1;
}



long receiveSerial() {
  Serial.begin(9600);
  long returnData = Serial.read();
  Serial.print("*");
  while (Serial.read() != "+") {
    unsigned long startTime2 = millis();
    if (millis - startTime = 5000) {
       return 0;
    }
  }
  Serial.print("^");
  return returnData;
}
