* Module: dns_sd_common.c
|
||
|
|
*
|
||
|
|
* Purpose: Announce the KISS over TCP service using DNS-SD, common functions
|
||
|
|
*
|
||
|
|
* 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.
|
||
|
|
*
|
||
|
|
* This module contains common functions needed on Linux and MacOS.
