how to send At commands to MC7354

hi, I am new to Sirrra modems. Just got several MC7354 along with dev kits.

Tried to install the drivers and two ports showed up in my windows device manager - DM port and NMEA port.

I tried to connect to DM port using putty (115200), but got no luck.

Tried to search on sierrawireless, but I didn’t see any document explaining how to set up the com port and connect to the dev port via putty…

As shown in the attachment, you can see ‘Sierra wireless WWAN modem’ under ‘modems’ section. You can right click on it and in the ‘properties’ window you will be able to see the corresponding port.
