Send Commands To Serial Port
All devices on Unix are mapped to a device file, the serial ports would be /dev/ttyS0 /dev/ttyS1. First have a look at the permissions on that file, lets assume you are using /dev/ttyS1. Ls -l /dev/ttyS1. You will want read.write access, if this is a shared system then you should consider the security consequences of opening it up for everyone. I've got a piece of code running on an Arduino board that will accept ASCII text commands on its serial port, and then will switch some relays based on which text commands you send it. I need to be able to run an automation script or batch file (on Windows XP and later only) that will switch the relays under certain conditions during an overnight test run. Sending Commands to Your Arduino From Your Computer This is a very basic tutorial to teach you how to send commands from your computer directly to your Arduino board. Keep in mind, this is a very basic code, but hopefully it will provide you a leg up if you want to try some more complicated things.

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