Hello, I have a TRB140 with Ethernet (RJ45 not USB) connection to network and PC.  All functioning well.  I need to send to AT commands to the modem (specifically to send/receive SMS messages).  Is this possible ?  (I see there are various other options available but these are not suitable (the s/w uses AT commands)).  I have seen references to using the CLI / Telnet but the terminal does not recognize AT commands.  Is there a direct method available ?

Thanks.

Hi,

A lot of AT commands could be avoided by using these commands right here:

https://wiki.teltonika-networks.com/view/AT_Commands#gsmctl_commands

But also, you can find that you can send AT commands through the same gsmctl:

 -A, --at <COMMAND>		 Send AT command to device

But if you're really looking for something, that isn't in the above:

use gsmctl -A <AT Command>

If you need a full AT manual for this device, please private message me and I'll send you the document.
