I don't know what /dev/ser1 is (unless it's a symlink), but if you know what you are talking about, OK.
You can see what comes back (if you have privilege to read /dev/ser1) with
cat /dev/ser1 ,
which can be subjected to the usual tricks such as redirecting, piping, etc.
Before doing any echos or cats, you probably want to set the I/O options with
stty [options] -F /dev/ser1
Consult the stty man page for details.
