I'm doing something similar with a ELO product and the documentation is very

The only thing I can see that you're doing wrong is: referencing ttyS0
(irq4). This is usually a communication port (serial, parallel, etc)
dmesg | grep ttyS
[ 1.023700] 00:09: ttyS0 at I/O 0x3f8 (irq = 4, base_baud = 115200) is a
[ 1.093439] 00:0a: ttyS1 at I/O 0x2f8 (irq = 3, base_baud = 115200) is a
