Entering AT commands for 4G modems
Starting with KeeneticOS 3.9, the support for entering AT commands via the router command-line interface (CLI) for 4G modems in NDIS (UsbLte) and QMI (UsbQmi) modes has been added.
The following command format is used to input AT commands:
for the UsbLte interface:
interface UsbLte0 tty send <at-command>
for the UsbQmi interface:
interface UsbQmi0 tty send <at-command>The full command syntax is as follows:
interface {name} tty send {command} [expect] [timeout]The AT command input for the Quectel EP06-E modem with UsbQmi interface is shown as an example:
(config)> interface UsbQmi0 tty send ATI
