[aprssig] Thinking about YAAC

[Brian Webster]

YAAC will work with older TNC's. Go to configure, expert, add port. Select
serial and then the TNC2 mode. The software will send the TNC in to kiss
mode. You can also enter any additional commands you want sent to the TNC as
well.

Thank You,
Brian N2KGC

For mobile use I will be using an RPi 3B+ with a TNC-Pi, so I won't need 
Direwolf in that application. The TNC-Pi will provide an adequate 
interface between the radio and computer.

For the base, I have a Linux desktop computer running Mint currently 
connected to an MFJ-1274 (MFJ-1270B with tuning indicator) to the radio. 
If I were to use Direwolf on the base, I would need to add a soundcard 
and homebrew some kind of interface for the PTT as well as fabricate new 
cables. Right now, I have a very simple configuration with a single 
serial cable going to the TNC and a single cable going from the TNC to 
the radio and it all works very well. At least with Xastir. With YAAC, 
however, I get nothing displaying on the map. In the configuration 
window for the interface where it has the TEST PORT button, I see plenty 
of data coming in from the TNC. Just nothing displays on the map or in 
the RAW DATA window.
