Does SQL Plus recognize any type of newline character from DBMS_OUTPUT?

Question

I am building a complex string inside a procedure and displaying with dbms_output.put_line. It works fine in SQL Developer but when I use it in SQL Plus it comes out goofy. It's been narrowed down to me using CHR(10) where I want line breaks. Is it possible to display a "formatted" varchar2 in SQL Plus as I'm expecting them? I even tried using .put with no luck.
Using:
Oracle 10.2.0.4.0
SQL Plus 10.2.0.1 / 9.2.something
Here's a small example:
set serverout on
set linesize 10
declare
  lv_string varchar2(32767);
begin
  for x in 1..5
  loop
    lv_string := lv_string || 'I AM LINE ' || to_char(x) || chr(10);
  end loop;
  dbms_output.put_line(lv_string);
end;
Expected Output (What I'm getting in SQL Developer):
I AM LINE 1
I AM LINE 2
I AM LINE 3
I AM LINE 4
I AM LINE 5
Actual Output (SQL Plus):
I AM LINE
1
I AM
LINE 2
I
AM LINE
3
I AM
LINE 4
I
AM LINE 5Right now I'm using a workaround, but would like to use a character (or combination of character) that SQL Plus will play nice with...if there are any.
declare
  lv_string     varchar2(32767);
  lv_start      pls_integer;
  lv_end        pls_integer := 0;
  c_newl        constant varchar2(1) := chr(10);
begin
  for x in 1..200
  loop
    lv_string := lv_string || 'I AM LINE ' || to_char(x) || c_newl;
  end loop;
  loop
    lv_start := lv_end + 1;
    lv_end := instr(lv_string, c_newl, lv_start);
    exit when lv_end <= lv_start;
    dbms_output.put_line(substr(lv_string, lv_start, lv_end- lv_start));
  end loop;
end;

Hi,
you need to increase your linesize:
SQL> declare
  2    lv_string varchar2(32767);
  3  begin
  4    for x in 1..5
  5    loop
  6      lv_string := lv_string || 'I AM LINE ' || to_char(x) || chr(10);
  7    end loop;
  8    dbms_output.put_line(lv_string);
  9  end;
10  /
I AM LINE
1
I AM
LINE 2
I
AM LINE
3
I AM
LINE 4
I
AM LINE 5
