I would like to send an ACII string over a com port using the linux terminal. How can I do that.

I am using Kubuntu 12.04

I am brand new to linux and serial communication. I just got an arduino. I got it up and running using the arduino serial manager. But I would like to use linux terminal instead so I will have more flexibility.

My arduino is /dev/ttyACM0

Thank you for help.

GNU Screen or something like that would do the job.

sudo apt-get update

sudo apt-get install screen

Then to connect to the board,

screen /dev/ttyACM0

You might have to change the baud rate, check the specs on the Arduino and read the screen manual to work out how to do that.
