Subject line says UNIX to DOS

I hope that means you are using a UNIX machine.

cat $1 | sed s/$/$'\x0d'/ >$
#            end of file
I have utils on MSDOS that add the cr to get the   crlf sequence
I wrote it for use in the rare occasion. (my definition of rare. :)

# rmcr.scr
# removes <cr> from text files
# Date: Feb. 2004
#   by: SLT
#     : file dressed up Dec. 2004
#   a literal <cr> follows first slash following the s.
echo $i1
cat $1 | sed s/^M// >$i1._cr
#            end of file
The ^M will needs to be entered at 'type in' time.
In vi  it is done by  pressing CTRL-V  CTRL-M in sequence
DO NOT CUT n PASTE that line!!!
I have never been able to use the $'\x0d' in this file.
The MSDOS programs don not run on Linux, per se.  'Ya Think' :)

crlf    \r \n     x'0D' x'0A'    CTRL-M  CTRL-J
carriage return, line feed    keep the pair in the order shown.

to use in UNIX:

(be in a bash shell)
for f in *.txt; do addcr.scr $f; done    # going to MSDOS

for f in *.txt; do rmcr.scr $f; done     # returning from MSDOS

if you run these on a binary - the binary is destroyed!!!

If you are in MSDOS, I have no help.
Well - see if you can find and download  FILT.EXE (ver 1.0)
   from the 1980 something era
FILT <Enter>  will present the helpfiles
It's what I use.  I set up batch (.BAT) files to expedite my desires.

Best of Luck
