MC7354 missing AT command Port


I am using a MC7354 module on the PCIe port of an Advantech MIO5251 running Windows Embedded Standard 7. The driver version is 4464.

In the serial ports, I see only DM and NMEA port, there is no AT command port available. Does anybody know how to enable the AT command port?

Thanks in advance


I believe no issues for that module because in serial port only shown DM and NMEA ports together with modem, network and USB ports. Actually “AT” triggering via DM port where can be access via windows “HyperTerm” or “Putty”. If no DO port then that module got issues.
