I think I can work through it all over time, but this project seems like it would be common, and maybe someone would like to inbox me even if they want a quick job to take on / consult on, or maybe someone is willing to share.? somehow bind(?) the PPP connection to my Ethernet port so all IP data is sent out via the PPP connection, and any data coming in the PPP connection is routed out. Make a PPP client connection (ras:) on that USB CDC port(s), i think this might not be to hard after CDC is working/. Get the CDC driver working so we can communicate with HE910 on the USB port (work out how to get one AT type command port and one for PPP), I tried changing device type to 'ttyACM0:' but no luck getting AT / OK response. I have a Laptop connected to the ethernet socket on the TWRSER which would be used to test the TWR Gateway solution (surf the net). The CDC driver i have not gotten to work as yet, I cant work out how to have multiple serial ports (one for AT one for PPP), I cant even get a single one to work, it does connect though. Telit HE910 modem eval kit (3G modem module) connected via USB to the TWR-SER USB port. TWR52259 MQX4.2 with TWRSER (Ethernet / Serial board) on the tower which all works fine

I have the following hardware connected on my desk: I wonder if someone would be willing to give some pointers / advice on how to go about making a simple 3G router out of the TWR52259 / TWR-SER board with MQX and a USB modem?
