### 4.8 The Protocol the Server Mode Uses.

Description of the protocol used to access `GPGSM`. `GPGSM` does implement the Assuan protocol and in addition provides a regular command line interface which exhibits a full client to this protocol (but uses internal linking). To start `gpgsm` as a server the command line the option `--server` must be used. Additional options are provided to select the communication method (i.e. the name of the socket).

We assume that the connection has already been established; see the Assuan manual for details.
