not able to send AT commands on on nrf9160 module

[vmskrshn]

When I connect on tera term and try sending AT commands, the device doesn't identify them, 

My prj.conf file looks like this:

I don't want to use AT_SHELL, so can u please suggest:

# Only enable bands: 2,4,12,13 This will provide coverage for the USA and Canada (Rogers, Telus, AT&T and Verizon).

# The rational: Limiting the bands will allow the modem to find a suitable network faster the first time.

# After running for a few days, the modem writes it's band history to NV and will remember

# the previous bands used which shortens the registration time. We can also remove this capability if

# are ok with long registration times for the first power up. Depending on our final unit

# test process, removing this logic would likely increase our test times. I am putting in for now.

I dont know what you mean by a sample. Can you explain?

[Øyvind]

I am very confused at the moment. What is the project you are working on? Where did you get that from and how did you start with the provided configuration in the OP?
