GRBAlpha - How to use digipeater or DNxD - 08. Settings of Direwolf

"Direwolf" works on Linux or Windows. You can get information from here: https://github.com/wb2osz/direwolf
You can download windows version from here: https://github.com/wb2osz/direwolf/releases
In case of Ubuntu, you can install it from "Ubuntu Software".
Direwolf is designed especially for APRS, but we can use it as a software TNC.

The settings of Direwolf are very simple. You only modify "direwolf.conf" file.

First, I explain in case of Linux.

After you install "Direwolf", you may have a file named as "direwolf.conf" at your home directory of your Linux PC.
If you cannnot find it, you can download an original file from here.
After you download the "direwolf.conf" file, save it in your home directory. Then open it with a text-editor.

To use 9600bps, you must find:
MODEM 1200
#MODEM 9600
The "#" means comment-out. The above setting means you use 1200bps and disable 9600bps.
If you want to use 9600bps for GRBAlpha, change them to:
#MODEM 1200
MODEM 9600

To enable to use your PTT, you have to modify:
PTT /dev/ttyUSB0 RTS
so as to suit your equipment settings.
For example, change "ttyUSB0" to "ttyUSB1", or "RTS" to "RTS -DTR", etc.
Before you use PTT setting above, you should set the permission for normal user on /dev/ttyUSB0. You must run a command in the terminal window like as:
sudo chmod o+wr /dev/ttyUSB0

Next, I explain in case of Windows.

After you install "Direwolf", you will find "direwolf.conf" file in your folder you installed "Direwolf". Then open it with notepad or other text-editor.

To use 9600bps, the setting is the same as Linux case above-mentioned.

To enble to use your PTT, you have to modify:
#PTT COM1 RTS
Delete "#" and modify to suit your equipment settings.
For example, change "COM1" to "COM2", or "RTS" to "RTS -DTR", etc.

About detail of settings, please read "User-Guide.pdf" file from here: https://github.com/wb2osz/direwolf/blob/master/doc/User-Guide.pdf

After modified your settings, you have to restart "Direwolf".
