Implementing support for a new modem- how to?

Hi All, We are working with this type of modem, and would like to submit patches to oFono. We found that we have to make few modifications to some of the AT command responses and also may have to introduce to support for a few new commands. We found that in network registration sms, call meter and gprs there are few AT command responses which differ from what is available in the generic AT modem of ofono. There are few new commands to be supported in network registration, gprs context etc, in order to support this modem. Do we need write new atom drivers even though the change is only in one of the AT command response?, or can we use the vendor variable (where ever available) to include this, as part of the generic at modem drivers? What is the recommended way to implement support for such a modem, so that we can start submitting patches? ------------------------------------------------------------------------ --------------------- Regards Arun Ravindran Specialist, Elektrobit OYJ Keilasatama 5, Espoo M: +358403445507 ---------------------------------------------------------------- Please note: This e-mail may contain confidential information intended solely for the addressee.
