Im trying to use bash to read from ttyS0 and need to set the following but im struggling to figure it out

databits = 7
stopbits = 2
parity = 0
flow control = 0

heres my code:

#!/bin/bash

# Port setting
stty -F /dev/ttyS0 raw speed 1200

# Loop
while [ 1 ]; 
do
    echo 'LOADING...'
    READ=`dd if=/dev/ttyS0 count=1`
    echo $READ


echo '[PRESS Ctrl + C TO EXIT]'
done

The script is working but I need to set the parameters. Any suggestions? And thanks:)
