* Module: dns_sd_macos.c
|

|
|
*
|

|
|
* Purpose: Announce the KISS over TCP service using MacOS dns-sd
|
||
|
|
*
|
||
|
|
* Description:
|
||
|
|
*
|
||
|
|
* Most people have typed in enough IP addresses and ports by now, and
|
||
|
|
* would rather just select an available TNC that is automatically
|
||
|
|
* discovered on the local network. Even more so on a mobile device
|
||
|
|
* such an Android or iOS phone or tablet.
|
||
|
|
*
|
||
|
|
* On MacOs, the announcement can be made through dns-sd.
