# Fibocom FM350-GL AT Commands Reference
Complete list of AT commands from **Fibocom FM350 AT Commands User Manual V2.10** (2023).
Source: `Fibocom_FM350_AT Commands User Manual_V2.10.pdf` in this repo.
**Tip:** To get the modem’s own list at runtime, use **`AT+CLAC`** (List of All Available AT Commands).
---
## Sending AT commands (FM350-GL)
```bash
cat /dev/ttyUSB1 & CAT_PID=$!
sleep 0.3
echo -e 'YOUR_COMMAND\r' > /dev/ttyUSB1
sleep 2
kill $CAT_PID 2>/dev/null
```
Use `/dev/ttyUSB1` when modem is in **USB Mode 40** (0e8d:7126). In Mode 41, AT commands do not work.
**If AT commands get no response:** run **`/usr/local/bin/diag-at-port.sh`** on the device to check serial ports, permissions, and which port responds to `AT`. See WEBGUI.md → Troubleshooting: No modem AT data.
