><P
>&#13;   Before you can set which port to use, you have to use this function to find
   out which ports exist.
   </P
><P
>&#13;
   If your program is interactive, you should present the user with this list to
   let them decide which port to use if there is more than one.  A
   non-interactive program (and probably interactive ones, too) should provide a
   command line option to choose the port. If <CODE
CLASS="parameter"
>maxports</CODE
> is <CODE
CLASS="constant"
>0</CODE
>, <CODE
CLASS="parameter"
>pinf</CODE
> can be
   <CODE
CLASS="constant"
>NULL</CODE
>, too.
