# WIZ750SR and AT Command

## Question

Asked by SerZTF on 2022-06-21 in Serial-to-Ethernet & ConfigTool.

Hi to all,
I have a question about AT commands on WIZ750SR:

After sent “+++” character sequence, is it possible send a command like

[AT+FDNS=www.google.com](http://AT+FDNS=www.google.com)\r\n
or
AT+NOPEN=C,173.194.126.168,80\r\n

(similar to how we do with WIZ5xx serires?)

Thanks to all who can help me.

Hi [@SerZTF](https://maker.wiznet.io/u/serztf),

You can use AT commands on WIZ750SR, but the command form is different from WIZ5XX series.
For details, please refer to the below link.

Thanks Rena for your reply.

I just looked through that manual, but I can’t find what I need.

I open another thread with my “specific” question about what I need to do.

Thanks again for your interest.
