I’m trying Sierra EM7455 with usb adapter connected to win 10/8/XP, using Tera term to test it:  
ATI  
OK  
AT!ENTERCND=“A710”  
ERROR

Who can tell me what’s wrong here, key or something else?

that means you are not using the AT command port of EM7455…  
You need to use modem port in device manager.
