3G connect scripts

[StoneWraith]

I've been following the forums for a while now and have made little progress getting my Sierra 3G modem to connect. I took the latest advice and attached a powered hub to the device (all are on AC and not batteries) but I am still unable to get it to connect. Can someone point me in the right direction to decypher the connection string so I can try to get my 250U to connect?

On the 3g page add the code below to it and try to connect.

*1199:0301*) echo "Sierra 250U detected. Attempting mode switch"
