For POP3 and a bunch of other stuff you need an IO layer that buffers
input and lets you read LF terminated strings, similar to
Ada.Text_IO.Get_Line.  eg

  type Socket_Type(Max_Line_Length: Positive)
  is new NC.Sockets.Socket_Type with private;

  procedure Get_Line(Socket  : in out Socket_Type;
                     Line    :    out String;
                     Last    :    out Natural;
                     Timeout : in     Duration := 30.0);
    -- Return Line(Line'first .. Last)
    -- Input up through LF if LF occurs,
    -- Line(Line'range) if no LF seen,
    -- or Input up through last received char if timeout or hangup
