When I have put the nRF9160 modem into mode 4 or 44, and then issue a status read AT+CFUN? command, the modem erroneously goes online.  I have used latest and greatest modem firmware, and still have the problem. I am using the at_client sample program.

This only happens when I use the LTE Link Monitor for my terminal -- not when I use TeraTerm. However, there is still a question I have in that case (in addition to wanting to know why LTE Link Monitor does what it does): Although I have tried to put the modem into all modes like 44, 21 and others -- reading back status shows me I always end up in either mode 0, 1, or 4. What about the others?

Do you have the "Automatic requests" check box checked? When this box is checked, with certain AT commands such as AT+CFUN?, LTE Link Monitor also sends other AT commands including AT+CFUN=1. Therefore you should uncheck this box if you want to know the true status of the modem.
