The Qualcomm MSM Interface is a binary protocol that seeks to replace the [https://en.wikipedia.org/wiki/Hayes_command_set Hayes AT command set] for [[Cellular|cellular modems]]. It defines a set of services:

* CTL -- control

* DMS -- device management

* UIM -- user identification module

* OMA -- open management alliance

On Linux, QMI is primarily driven through the [https://www.freedesktop.org/software/libqmi/libqmi-glib/latest/ qmi-glib] library and the [https://www.freedesktop.org/wiki/Software/libqmi/ qmicli] tool. A client context must be acquired from the CTL service to use most other services.

A client context must be acquired from the CTL service to use most other services. Services implement "Requests" and "Indications": indications are sent to subscribed clients, while requests are bound to a client context, pipelined, and can be answered out of order. Input and output arguments are defined as TLVs (Type-Length Values).
