Hello, Some of you might like to know about a project I released: https://github.com/scintill/qmiserial2qmuxd It's a small Linux/Android program to allow projects such as libqmi to work with qmuxd. It emulates the serial cdc-wdm interface and passes QMI messages back and forth between qmuxd and a client. There's a README on Github with more information. It hasn't been tested very thoroughly yet (I've done several QMI requests on my Samsung GS4 Mini phone), so I'd welcome your feedback, contributions, and questions. For me it's a stepping stone in creating a free Android RIL (early-stage code at https://github.com/scintill/android_frameworks_opt_telephony_ril_ofono ), but hopefully some others can get good use out of it too! Cheers, Joey
