Serial modems support for Win10 IoT Core ARM64

Greetings,
We're trying to enable an old Siemens mc35i serial modem on NXP iMX8 based board under Windows 10 IoT Core. Are there any modem drivers and higher level stack (ppp?) available for serial modems at all, specifically for ARM64? If yes, any guidance on modem enablement and further connection setup is greatly appreciated.

Best regards,
Gennady Kuznetsov

    I can not find the modem driver which is available for Siemens mc35i. What i can find is an open source of the driver working with Siemens mc35i. You may try to build it for Windows IoT Core ARM64, and then follow this document to add the driver to the ffu image. I'm not sure that will work since i have no device to test. In addition, Windows IoT Core on NXP iMX includes serial driver imxuart, it allow user to build the serial communication.

    Thank you Michael!
    Could you please point me to that open source driver? Are there any serial modem drivers included for ARM64 at all now (hoping for reverse compatibility or supported alternative to Siemens mc35i)?

    How does modem support look like in IoT Core, are there any high level stacks to enable networking over 3G/LTE?

    We already can communicate with the modem on AT command level, but hope for a more convenient way.
