# AT APDU Backend
|
|
|
|
The AT Backend is used to communicate with the eUICC via AT commands over a serial interface.
|
|
It is commonly used with cellular modems that support AT commands for SIM card management.
|
|
|
|
## Unix-like platform
|
|
|
|
If you need to allow **non-root** users to access serial ports, read the following article

|
|
(Ubuntu)
|

## Environment Variables
|
|
|
|
- `LPAC_APDU_AT_DEVICE`: specify which serial port device will be used by AT APDU backend. \
|
|
([string](types.md#string-type), default: `/dev/ttyUSB0` on Unix-like platform and `COM3` on Windows)
|
|
- `LPAC_APDU_AT_DEBUG`: enable debug output for AT APDU backend. \
|
|
([boolean](types.md#boolean-type), default: `false`)
