The system contains a tool called mpt which allows to route some of the MSM modem traffic to the microUSB connection and such enables a passthru mode where the host PC could use the modem directly. That way the modem can be configured with some special software from Quallcom.

root@castle:/var/home/root# mpt
Usage:
To enable passthru: mpt [port_spec]
To disable passthru: mpt disable (or mpt x)

[port_spec]
dun (or '0')       : DUN (port0) only
diag (or 'd')      : Diag port only
dun,diag (or '0d') : DUN (port0) and Diag port
diag,gps           : Diag port and GPS port
userial            : Serial passthru with USB cable
serial             : Serial passthru with Serial cable

Sadly a special USB driver is needed for this. It shows up like this on my linux box:
