Can't you use hardware or software flow control?  What about monitor the
UART and using interrupt driven communications?

normally when you communicate with a serial port, you should send the
message and then put the current thread to sleep for a while. It can be a
couple of seconds - thats all you need. Thread has a method sleep() that
takes the number of milliseconds to sleep as an int parameter

// code for sending message to serial connection
try {
  Thread.sleep(2000);
} catch(Exception e) {
   // sommat went wrong
}
