Quit ``` *Fig. 41 – WIFI setup program* **.uart** is not very complicated but it's quite temperamental especially if you use a PS/2 keyboard. You will need to use the standard ZX Spectrum keys; **CAPS SHIFT** + **0** for **DELETE**, **SYMBOL SHIFT** + **K** for +, **SYMBOL SHIFT** + **C** for **?**, **SYMBOL SHIFT** + **P** for ", **SYMBOL SHIFT** + **N** for **,** and **SYMBOL SHIFT** + **L** for =. You run it by issuing a: ``` .uart ``` you will be greeted by a screen full of information that will end in an **L** cursor. To test type the following: ``` AT ``` and press **ENTER** If you're good so far, the *ESP* will be responding with: ``` OK ``` That's a very good sign. That means serial communications have been established. To see however if the *ESP* is actually working you'll need to issue a few more commands. Type: ``` AT+CWMODE? ``` the *ESP* there should respond with a **1**, **2** or **3** (this is the mode that's its working at; being **1** for Station, **2** for Access Point and **3** for both). Normally this should be enough to verify your *ESP* is working but if you want to take it one step further, you should set the *ESP* to station mode by giving: ``` AT+CWMODE=1 ``` then check for what Access Points are around by doing: ``` AT+CWLAP ``` before finally connecting to one by giving the command: ``` AT+CWJAP="SSID","YourPass" ``` where *SSID* is the name of your network and *YourPass* is your WiFi password. The *ESP* will retain these so you can do if you want: ``` AT+RST ```
