Yes, I was wondering if I read that right, but it seems that AT commands are still in use.
Us BBS nerds used to know AT commands by heart. We would send instructions to our 2400 baud Hayes modems using QModem:
ATZ = reset
ATDT1234 = dial 1234 on a touch tone phone (DP for pulse dial)
Those of us who later moved to US Robotics modems started learning proprietary USR ampersand codes.

- bri3d 8y agoMany peripherals with serial interfaces still use AT commands - Bluetooth <-> Serial adapters, the original ESP2866 firmwares where it was a Wifi-to-Serial adapter, most Serial <-> CANBus/OBD adapters like ELM327, basebands all spring to mind.
