RUT955 read RS232 serial stream

Hi, I need to read direct stream from /dev/rs232
I’m currently setting baud rate using stty -F /dev/rs232 19200
And reading stream through cat /dev/rs232

The problem is that the stream I’m trying to read does not contain newlines so I don’t receive any data.
Also even when I try to send data to the serial port from a terminal (with newline) I only receive one message every 2/3 messages. It’s like other services are consuming data on the serial port

Why am I receiving only few messages?
Is there a better way to achive this?
