Hi everyone,
I have a Huawei E397 4G/LTE dongle, and I am able to connect it
by doing some tinkering here and there(modeswitch,udev...) via both networkmanger and wvdial. But it only connects in 3G mode, so how can i make it connect in 4G mode?

Also I tired connecting it via minicom and send some AT command that I read somewhere on the internet but there is no OK response from AT command even though I enabled local echo.

os: slackware64-multilib 14.1

Update: fixed minicom issue, but the command is not supported.

PS: I apologize for my bad english.
