Cinterion EHS6T - Can't enter AT commands in Tera Term | Thales IoT Developer Community

Hello. We have the Cinterion EHS6T gsm modem which I am testing with a AT&T sim. I'm using Tera Term to test with the goal to send/receive SMS however I can't enter any commands. I know other carriers have special sims for devices like these however AT&T hasn't been much help. I read in another forum thread that this modem will take a standard sim but I've tested two now with a text plan on them and can't enter any commands. I'm new to this so can you please offer some suggestions? Thanks.
