How are you *trying* to write to the serial port? What is connected to
the port?  How is it connected?  DTR/RTS is hardware flow control,
used to determine whether the device you are attempting to write to is
ready to receive data. Hardware flow control requires that certain
pins be connected in the cable.  Incorrect pinouts on the cable's
connectors may be your problem.
