Don't use QSerialPortInfo::isBusy() to filter available ports 

The above  member opens the  port and  that twiddles DTR/RTS  which is
unhelpful if they are connected to  PTT. Instead a primitive port name
filter  to try  and  detect unuseable  ends of  serial  port pairs  is
employed. This may  need further tests to exclude  similar devices yet
to be discovered.
