When hamlib is enabled, 3 clickable buttons are added to the QSO frame, so you
can easily fill in frequency, mode and signal strength in the appropriate
fields. If your log records power (required in some countries), there is also a
clickable power button in the QSO frame. You can either chose to poll your
rig continuously with a certain time interval or just retrieve rig data
when using "Edit Click All" or Ctrl-k. Your hamlib port can be configured
in the hamlib page of the preferences dialog. You can enter things like:
rts_state=ON,timeout=600,serial_speed=19200 here.
