hmmm

I've had a thought in the back of my mind for a few months, and it seems like nobody on the English internet has talked about it on any open forum so I can't seem to find information about it. Has anyone tried to mess around with the new Quectel and SIMCOM Mini PCIe 5g GSM cards to get the Mobile Network feature working on a desktop and get eSim compatibility in Windows 11 like those fancy new laptops have? Both of the mentioned manufacturers offer both mini PCIe and M2 options, I'm just wondering if the drivers are plug and play and if anyone has tried this before? I'm obviously aware of USB GSM Modems which have multiple physically embedded serial ports with SIM Card slots, but there is also no eSIM alternative to these currently publicly available to civilians. Discuss.

>>79747 why would the drivers not be plug and play...? The problem is writing the feature-complete program that will use that device file with no documentation on the drivers

>>79938 Because maybe the manufacturer would want the client to make their own driver (IE, Dell makes a laptop with a chip from a manufacturer and is expected to make their own driver). It's more of a question as to how the driver (if any) serializes the hardware on an OS such as Windows 11. Is it able to be interfaced with as a network accessory off rip or does it need to be interfaced with using a special software for GSM modems, etc.

>>79978 The serialization of hardware is done by the firmware on the chip and the transactions happen through standard protocols (i2c, uart, comi), drivers come with the OS and interact with the controller on the motherboard through serial ports to interact with the devices connected to the controller through the physical connectors If you are using windows the drivers it came with will likely work since hardware manufacturers always keep compatibility with some common piece of hardware (think nvidia gpus being compatible with cirrus vga from like the 1980s) In case you are confused we did use to use the drivers built into the firmware back when plug and play BIOS was a thing, but that was a garbage practice and no good operating systems relied on BIOS. Though maybe you have already tinkered and seen it werkz

post sounds messy because i omitted that the serial ports protocols are built into the firmware, any write to serial ports trigger a system management interrupt and firmware will pulse lines through the speciel ports that are mapped to lines
