Perhaps the problem is that the line is delimited by cr-lf and backslash
doesn't escape the whole two-char pair.  Perhaps the file subsemi.sed should
have unix eol (just lf) instead of dos eof.

Another approach would be to use a more complex sed program:

:start
h
s/;.*/;/
t cont
b
:cont
p
g
s/^[^;]*;//
t start

Again, put this into the file subsemi.sed, and run
        sed -f subsemi.sed <input >output

I do it by one of the following commands in unix:

recode /lf../ <infile >outfile
tr -d '\r' <infile >outfile

But I'm afraid it won't help in your case, I don't use DOS.

Have a nice day,
