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?
card EN7455
adapter USB
how about typing ati3 ?
ATI3
SoftK56V_B2.1_V7.70.00
OK
What does this mean ? )
that means you are not using the AT command port of EM7455…
You need to use modem port in device manager.
Thanks
So I have to change Tera’s settings
