hum, copy/paste mistake in this post:
cat /dev/ttyS0 | sed -e 's/[^M]/ /' | awk '{ if(match($0,":")) printf
"%s", $0; else printf "%s\n", $0 }' >> /home/christophe/alarme/$(date

If you use sed to remove the ^M characters, you have to use a real
ctrl-M, not the two characters '^M'. It would be better to add
gsub(/\015/," ",$0) to the awk command.
