I think the EditText expects {0D, 0A} or {0A, 0D} at the end of each line. So
after removing the last character of each line, try appending "\n\r" or "\r\n". I
think one of those should do it.

<code>
end_of_line = "\n\r" -- or "\r\n"
while 1 do
    line = gets(fh)
    if atom(line) then
        exit  
    end if
    data &= line[1..length( line)-1] & end_of_line
end while
