It is right

#ls -l file*
-rw-r--r-- 1 root root 7 2010-09-17 10:13 file1

Excellent. Try next.

#rm -f file*
#/usr/local/bin/qemu -serial file:file1 -serial file:file2 -serial 
file:file3 -serial none hd.img
isa irq 4 already assigned

Misfire. Try next.

#/usr/local/bin/qemu -serial none -serial none -serial file:file3 
-serial file:file4 hd.img

In VM

#echo test1 >/dev/ttyS0
#echo test2 >/dev/ttyS1
#echo test3 >/dev/ttyS2
... error...
#echo test4 >/dev/ttyS3
... error...

OOPS! Surprise.

#halt


In host

#ls -l file*
-rw-r--r-- 1 root root 7 2010-09-17 10:40 file3
-rw-r--r-- 1 root root  7 2010-09-17 10:40 file4

In this case expected.
