43<H2>Description</H2>
44<P>Sets the child send capacity. The send capacity must be a multiple of 2, so if an odd number is designated, it is rounded up so that it is even. Be sure to use this function after referring to the &quot;Wireless Communication Library Description&quot; for thorough understanding.</P>
45<P>The child device's sending capacity is initialized by the <A href="WM_StartParent.html"><CODE>WM_StartParent</CODE></A> and <A href="WM_StartConnect.html"><CODE>WM_StartConnect</CODE></A> functions. This cannot be reset to a value larger than the initial value.</P>
46<P>This wrapper function calls the <A href="WM_SetMPParameter.html"><CODE>WM_SetMPParameter</CODE></A> function internally.</P>
