Any idea what format this port speaks?  Some Huawei Qualcomm-based
devices still use a TTY driver but send/receive 16-bit 8000hz PCM audio
frames via a serial port.  If the D-Link does something similar, it may
still make sense to drive it via option.

MI_05 D-Link HSPA+DataCard Debug Port

If it's FCCID KA2WM158B1 then it's a Qualcomm device, and this port may
be a DIAG port.  It should also be driven by option if that's the case.

I looked but couldn't find downloadable drivers for the DWM-158 so I
couldn't double-check myself.

This is a DWM-158D1 or maybe they have versioned it E1, it is Mediatek based. Most (all?) of new D-Link modems are made by BroadMobi using Mediatek chipset and having an additional AT cmdset in the AT+BM form.
