1. If the operating system says the device exists, eg
Code:
ls >/dev/ttyS0

if that does not return an error, the serial port is configured for the OS.

2. The next part is RS232 debugging, here always start with a known working terminal and go through the different combinations with a null-modem and even a break-out-box.
