AT Port

How to find AT Port:

Method 1:

# mmcli -m 0 | grep ttyUSB
           |                   ports: cdc-wdm0 (qmi), ttyUSB4 (qcdm), ttyUSB5 (gps),
           |                          ttyUSB6 (at), ttyUSB7 (at), wwan0 (net)

ttyUSB6 and ttyUSB7 are for the ports for AT command.

Method 2:

# dmesg | grep ttyUSB
[    5.574612] usb 3-1: cp210x converter now attached to ttyUSB0
[    5.586590] usb 3-1: cp210x converter now attached to ttyUSB1
[    5.598584] usb 3-1: cp210x converter now attached to ttyUSB2
[    5.610583] usb 3-1: cp210x converter now attached to ttyUSB3
[   18.535820] usb 2-1: GSM modem (1-port) converter now attached to ttyUSB4
[   18.542643] usb 2-1: GSM modem (1-port) converter now attached to ttyUSB5
[   18.548504] usb 2-1: GSM modem (1-port) converter now attached to ttyUSB6
[   18.553115] usb 2-1: GSM modem (1-port) converter now attached to ttyUSB7

ttyUSB4 to ttyUSB7 are ports for GSM modem.
And ttyUSB6 (the second port counted backwords) is the port for AT command.
