If you put a breakout box on the serial port you will see that the
Windows serial port driver drops the DTR signal every time the device
is closed. The device is closed each and everytime K95 terminates
unless the device handle was passed to K95 when it is started. When
DTR is dropped the modem hangs up the phone call.
