Snapdragon 8 gen 3 PCI Express

[phodina]

Hi,
I have laptop with Snapdragon 8 gen 3 (Lenovo x13s) and it has Qualcomm modem.

However, this modem is connected over PCIe on the board. In the help I have not found this option.

Could you please give a hint which parts of the Python code to modify to allow connection over PCIe?

Here's the modem manager output:

(venv) ~/QCSuper $ ./qcsuper.py

I'm using Alpine linux on the machine:

The /dev/wwan0qcdm0 seems to not be a normal TTY device which is also used by the serial modem. We also have similar issue on SCAT too: fgsect/scat#97
