### Virtual serial port
If the `-s` command line argument is specified, then kappanhang will create a
**virtual serial port**, so other apps which don't support Hamlib can access

### Icom IC-705 Wi-Fi notes
Note that the built-in Wi-Fi in the Icom IC-705 has **very limited range**,
and **sensitive to interference**. If you see a lot of retransmits in the log,
or packet loss, then:
- Place the IC-705 close to your Wi-Fi AP/router, or use a Wi-Fi range
extender device
- Make sure the Wi-Fi bandwith is set to max. 20Mhz in the Wi-Fi router (see
explanation [here](https://superuser.com/questions/542191/does-moving-my-router-from-20mhz-to-40-mhz-increase-my-wireless-speed))
- Try switching Wi-Fi channel on your Wi-Fi router. Only channels 1, 6 or 11
should be used (see explanation [here](https://www.metageek.com/training/resources/why-channels-1-6-11.html))
Sometimes rebooting the transceiver helps, as the network stack in the IC-705
is not quite free of bugs. :)
