B.12.2 Modem Interface Not Activated

For some OPTION UMTS Sticks it may occur that the Modem interface which is needed for pppd is not activated.

Example using GIO225 adapter

check via:
grep "" /sys/bus/usb/devices/*/tty/*/hsotype

Output should look like this:
/sys/bus/usb/devices/2-1:1.0/tty/ttyHS0/hsotype:Control
/sys/bus/usb/devices/2-1:1.0/tty/ttyHS1/hsotype:Application
/sys/bus/usb/devices/2-1:1.1/tty/ttyHS2/hsotype:Diagnostic

hsotype:Modem is missing here.

Check the interface configuration via this comman:
chat -e -t 1 '' "AT_OIFC?" OK >/dev/ttyHS0 </dev/ttyHS0

Output should look like this:
AT_OIFC?
_OIFC: 3,1,1,0

OK

If you see this
AT_OIFC?
_OIFC: 2,1,1,0

OK

you can activate the modem interface via the command:
chat -e -t 1 '' "AT_OIFC=3,1,1,0" OK >/dev/ttyHS0 </dev/ttyHS0

After that unplug the adapter and replug it afterwards.
Now check via:
grep "" /sys/bus/usb/devices/*/tty/*/hsotype

for a modem entry.
/sys/bus/usb/devices/2-1:1.0/tty/ttyHS0/hsotype:Control
/sys/bus/usb/devices/2-1:1.0/tty/ttyHS1/hsotype:Application
/sys/bus/usb/devices/2-1:1.1/tty/ttyHS2/hsotype:Diagnostic
/sys/bus/usb/devices/2-1:1.2/tty/ttyHS3/hsotype:Modem
