ParticipantDo we have a list of the ADSL modem drivers that will be in the release version with USB host functionality?
I.E – What ADSL modems will we be able to drive?
Have we any recommendations on how to run a PPP fail over for if an ADSL link is down?

November 26, 2010 at 12:04 pm #3061ParticipantScript I am using to build the CDP into a Dial on Demand router using EDGE.
Next step will be to do the same with a GPRS version of the DCP with an ADSL modem as the primary link.
Below is the configuration script I’ve used using Teraterm as a scripting tool.
; Application script applying cellular router functionality to the CDP

ParticipantHas any-one any sample code that could be added to a router script to give an ADSL ( USB or Ethernet ) modem as the primary link and use the on board Cellular modem for a fail over solution?
