AT Command Reference
80-99208-1 Rev. D 6-37
As shown in the syntax above, either <DCE_by_DTE> or
<DTE_by_DCE> can be optionally specified. If only one value is
specified then the other is left unchanged. If both values are
left unspecified then both are reset to their power-on default
values.
Optional parameters must be separated by commas. The
commas act as place holders (in the command parser) for any
missing optional parameter.
+IFC? queries for the current settings of <DCE_by_DTE> and
<DTE_by_DCE>. +IFC=? queries for the acceptable ranges of
<DCE_by_DTE> and <DTE_by_DCE>.
