FLAGS is a bit vector and controls how the function acts:

Bit 0: If cleared a simple pipe based server is expected and the

function behaves similar to `assuan_pipe_connect'.

If set a server based on full-duplex pipes is expected. Such

It also enables features only available with such servers.

started as a background process. This flag is useful under
