How can I send data to the serial port from a Linux shell?

Question

I need to find the linux way of running the following DOS commands:

MODE COM1: 9600,N,8,1,P
COPY FIRMWARE.COD COM1 

Is this possible? I know COM1 in Linux is /dev/ttyS0 but that's about it. How do you set the mode on it and perform the copy?

Answer 1

Set tty device settings:

stty -F /dev/ttyS0 9600 -parity cs8 -cstopb

Send data:

cat firmware.cod > /dev/ttyS0
