cmake: Avoid try_run when cross-compiling
'A' uses mark and space filters but simpler and cleaner than earlier attempts. New 'B' uses a different technique where the demodulated signal is proportional to the frequency.
(including 1200/2200Hz) to -x command line argument in Direwolf. This is useful for calibrating FM deviation using a meter, devcal, or manually. See: https://groups.io/g/direwolf/topic/setting_deviation/78633292 Options are: -x a: alternating mark/space tones (original functionality) -x m or -x 1: steady mark tone (e.g. 1200Hz) -x s or -x 2: steady space tone (e.g. 2200Hz) -x p: set PTT only - for RTL-SDR adjustments Scope tested with mark_freq>=300Hz and space_freq<=5000Hz. Returns an error message if mark/space frequencies are set to 0.
This allows client applications to locate the IP addresses and the port of the KISS TCP service, allowing the end user to just select a Dire Wolf from a list instead of trying to guess its dynamic IP address and typing it in manually. This is especially convenient on mobile devices. On Linux, the standard Avahi daemon is used via dbus and the avahi-client library. Building with it requires installing the development header package; README.md is updated accordingly. On Mac, the MacOS dnssd API is used: https://developer.apple.com/documentation/dnssd?language=objc I don't have Windows, but more recent Windows 10 builds apparently have a working DNS-SD mDNS implementation that can be used on 64-bit builds.

We were checking `*t` for end of string instead of `*c`, but `t` never changes, so we would run off of the end of the buffer and output a very large number of config errors before eventually crashing.

Hello John,
My name is Jason Kim (KG6KZZ). I would like to thank you for your work on Direwolf TNC development. This had been a great learning experience using it and trying on tweaking the software on my Windows 10 system.
I was able to make few improvements on the software downloaded from your GitHub v1.7 Dev branch, but, unable to push my changes for your review.
Since I am still learning to use GitHub, I am having bit of difficulty getting over the GitHub push authentication errors.
Anyhow, what I wanted to propose is to add support for using CM108 GPIO in Opendrain mode for PTT activation. This eliminates the need for adding external Open Collector Transistor for pulling down on PTT pin, which simplifies the HW modification needed for CM108 USB audio cards.
In so doing, I had to correct few issues relating to Windows 10 operations as listed below. Attached is my edited source files with my change notes with "KG6KZZ" comments on the files for your reference.
Please let me know if these could be accommodated.
Thank you.
Jason Kim
