----------
An excellent guess. The beep is a stand-in symbol meaning that
the UART (the serial port chip) has detected one or more arriving bytes
has overwritten a preceding byte before being read. In short, bytes have
been lost. Most often it is other things in the machine blocking access
to the serial port for short but important intervals. Those things are
either software (TSRs) or hardware periperials.
