Hi Kekien,
Yes they are the same as described in that other query that you referred to.
In general it is fairly easy to test these out yourself:
1) Connect your RUT240 to the internet and access its WEBUI
2) Navigate to Services -> Mobile utilities -> SMS Gateway -> Post/Get. Enable the service, put username and password. Click Save and Apply.
3) Open a new webpage and type in the post /get commands that you can find at: https://wiki.teltonika-networks.com/view/RUT240_Mobile_Utilities#Post.2FGet
For example, if you wanna test it, use the following syntax and put the wrong password:
http://192.168.1.1/cgi-bin/sms_list?username=user1&password=user_pass
You will get a response with Bad username or password. In similar manner other commands can be tested.
Best Regards,
