When I run at!band=14,"B12",0,0000000000000800 I just get an ERROR
You get an error because your modem's hardware doesn't support that band.
Keep in mind you can only set the bands which are supported by your modem's hardware.

Did you first install the Sierra Wireless driver software for Windows?

Both computers seem to actually recognize and install the modem, I can see it in device manager.. just don't get why I can't get this terminal to work.

Modems usually create multiple ports in device manager under "Modems" and Ports (Com & LPT), depending on the mode the modem is in (MBIM/QMI/etc.)
In the terminal app make sure you select the com port which is under "Modems", not Ports (Com & LPT) which are used for diagnostics purposes only.

Hello, I am trying to band lock my EM7565 using GoldenOrb to Band 5, Band 13, and Band 66 on Verizon. I am having a really hard time understanding these AT Commands and I do not want to do the wrong thing. Can someone post the AT commands in the order I need to do it in and a brief explanation? Sorry, don't mean to be demanding or anything. I really want to learn! Thank you for any help :D

Do you already have the system up and running and can connect to the internet? Also what is your reasoning behind locking bands. A lot of times the em7565 is happier and more stable when not band locked with signal permitting

Yes, I am up and running and connected to the internet. For where I live, there are only a few bands that reach out to me. It seems to want to stay connected to Band 2 and aggregate with Band 66. Which is fine, but Band 2 in my area is a very poor signal. When Band 5 is selected and aggregated with Band 66 it seem to provide a more stable connection and better ratio of D/L and U/L. Also, Band 13 is the best band out here for the most stable connection and would like to test out how grouping B5+B13+B66 would be. And also to learn :)
