the output format for sed and awk

[PAN TAO]

hello,all

I would like to use sed and awk to deal some text with
dos text format(CRLF), but I found the output of sed and
awk format is in unix textfile format. Can I let the sed 
and awk to output dos text file format? I found while 
install cygwin, there is an option for 
"default text file format", the option is "dos" and "unix".
I forget what I set while I installed my cygwin. Can I 
adjust the setting and will it resolve my problem? 

many thanks,
