Before you can use a TNC with Win-Test, it should first be tested with a simple terminal program like Hyperterm provided with Windows. Do not try to get started with PAXON or other elusive software!
When you turn on the TNC, the startup message will tell you, what kind of software you have.

The following messages are displayed on a Symek TNC2H using TF mode:

In TF mode, commands are sent to the TNC using [Escape] followed by a command character. [Escape] I for example will allow you to set the outgoing callsign and to connect to a station, use [Escape] C. Here is a sample session. When pressing the Escape key, the TNC displays an asterisk followed by a blank character.

TNCs in the TAPR mode, usually come up this way, or similar. Most characteristic for TAPR is the cmd: prompt. By the way, most TAPR TNCs use 7E1 (7 data bits - Even parity - 1 stop bit) COM port settings at 9600 baud, which is different from the typical 8N1 (8 data bits - No parity - 1 stop bit) settings.

At the cmd: prompt you are able to enter commands. Let's do a simple session in TAPR mode to make it clear.

Initially we set the outgoing and then connect. Note that the cmd: prompt goes away the moment you are connected.
Win-Test TNC set-up
To set-up TNC, open the menu Options | Configure Interfaces. Set up the correct COM port parameters, the same as before in the terminal program.
Testing the Setup
To verify that the TNC set-up and the connection are correct, open the DX-Cluster monitor window (Alt+O). After powering on the TNC, the startup message should appear as before in the terminal program. If this works fine, proceed - else try to find the problem.
Once you have configured the appropriate COM port for your TNC in Win-Test, you should be able to connect to your local node.
Open the DX cluster window by using Alt+T to send a command to the TNC.
To control the TNC, you may need to send an Escape character (in TF mode). Pressing [Escape] in the DX-Cluster window is not possible because the window would close. To send [Escape] to the TNC, you must press Ctrl-E.
The following information is provided for a TNC in TF mode. TAPR works accordingly, but commands are different.
Check first if your call sign is already saved in the TNC. If not, no connection is possible. To check your call sign type in DX cluster window: Ctrl+E I. You can now see the TNC reply in the monitor window, e.g.: NO CALL or DL8NAS. If the call sign is not correct, type: Ctrl-E I <call> (Ctrl-I DL8NAS)
Channels are used to establish several AX.25 connections at the same time. After power-on, the TNC is usually on channel 0, where no connection is possible, only monitor mode. The command to change to channel 1 is: Ctrl-E S1. Message in monitor window: CHANNEL NOT CONNECTED
The connect command to your local node: Ctrl-E C<node> where <node> is the callsign of your local node.
You can follow how the connection is built in the DX-cluster monitor window. When connection is established, you may want to connect to your preferred DX-Cluster. It is important, that all commands after the initial connect are to be sent without a leading [Escape]! These are normal inputs in the DX-cluster window, e.g.: C DB0SDF-7 where C is the connect command to your local node, to connect to the DX cluster DB0SDF-7.
After connection to your preferred DX-cluster, you can use the buttons of the DX-CL window to list DX announcements or solar information. You can use the packet monitor window (Alt+O) to check the connection status and to see data are coming in from the TNC. Spots should begin filling up the bandmap at this stage.
If no DX announcements arrive in that window, check the DX-Cluster options set-up:
To leave the DX cluster, use bye command in the DX-Cluster window. After reconnect to your local node, type the TNC command CTRL+E D to disconnect from your local node.
Other important TNC commands are:
CTRL+E T16: set TX delay, normally around 16 (12..20)
