Serial Communication Arduino Electric IMP - missing bits

i missing last few characters when sending string imp , arduino.
i running 19200 baud, pin 8.9 on software serial.
this code. individual characters read,however last few (varying) not added indata string reason???


  // read serial empty
  string indata = "";

  while (impserial.available() > 0)
  {
    char character = impserial.read();
    indata += character;
    serial.println(character);
    delay(10);
  }
  serial.println(indata);

  // print out on screen
  messageprint(indata);
