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

When loading usbserial with the USB IDs we get two serial devices when using dun mode:
root@castle:/var/home/root# mpt dun

If your device gets stuck in diag mode, use #*USBPASS# to turn it off. You may need a code to do this, which you can get from http://www.herrie.org/tpkeygen.html
