RB411 and Sierra MC8705 fotr GPS

Hi,

The Sierra MC8705 is a 3G modem and GPS. I’ve conected it to a RB411 and I can connect to the intenert without problems. Great!

Now I would want to get some GPS data from the card. Sierra manual says that GPS information can be obtained using some AT commands, but I am unable to connect to the modem:

/system serial-terminal usb2 channel=0

stalls and waits until Ctrl-A Q is typed. Any other channel returns a “failure: no such channel” message

Does anybody know how to get GPS information from this modem? This is the output of /port print and /system resource usb print

/port print
Flags: I - inactive
