When line conditions are stable, quick connect results in shortened connect times;
however, significant fluctuation in line conditions from call to call can cause longer
connect times; thus, it may be advisable to disable quick connect.

modem may produce a Ring event code after the DRON message if enabled by the y
parameter. The y parameter must be set to a value equal to or smaller than the
expected ring cadence in order to pass the report to the DTE.
