AT Commands are instructions for modems. The AT is short for attention, which is why all the instructions for the modem start with AT. Some examples of AT commands are ATD (Dial), ATA (Answer), ATO (Return to online data state), and ATH (Hook control). These commands are used for machine-to-machine communication, typically between the modem and computers and devices.
You can find an AT Command manual on the Thales website. However, a better approach is to contact a Novotech sales representative who can procure the AT command manual for you so your developers and designers don’t have to waste time looking for it online.
This is just one of the many benefits of directly acquiring routers, modems, modules, and other connectivity devices from Novotech.
