Just running Ubuntu for the first time by booting to USB drive. Now I have plugged in a USB-to-Serial converter which has been recognized and automatically added as /dev/ttyUSB0

Use one of screen's lesser known features:

screen /dev/ttyUSB0

if you need to specify the baud rate, add it after the serial device. eg, for 57600 baud: screen /dev/ttyUSB0 57600 – Jeremy Kerr Mar 13 '12 at 12:45

You can use putty. Its an ssh/serial/telnet client for Windows and Linux. You can download it from

you can use ckermit also. It should be in the repository. After installing it create a file in your home directory called .mykermrc then add the 5 following lines:

set line /dev/ttyUSB0   
set flow-control none  
set carrier-watch off  
set speed 115200  

parameters can be adjusted as necessary.
save the file.
to start it

sudo kermit

Needed Mint 17.1 to talk to my Arduino, after a little chasing around, the best way I found was to either:

sudo gedit /etc/group

goto line...


add your "username"


save file

or use

Administration - Users & Groups - Manage Groups

goto line "dialout" check properties to ensure that "username " is ticked if not "username" must be added.

This worked for me and by the look of lots of posts others have had the same problem. Hope this helps guys.

-1 for sudo gedit /etc/group. Don't. Just don't. Learn how to add a user to a group using usermod or adduser for example. And your post is more of a comment rather than an answer to the question, because you don't actually show how to connect. – gertvdijk Dec 24 '14 at 14:36

I was using puTTY to connect to the serial ports. But don't forget to add your user to dialout: sudo adduser <username> dialout then reboot the system. After that, you can use puTTY for serial connections such as /dev/ttyUSB0.

it is actually enough to simply log out and back in again. – Atsch Jul 24 '15 at 19:04

You could use tio - a simple tty terminal I/O application:

tio /dev/ttyUSB0

Using Lucid and a Dynamode USB to RS232 cable:

Plugged it in
ran kermit
set line /dev/ttyUSB0    <<-- mind the capitals/lowecase
set speed 9600

and successfully connected to an RS232 port on an OpenVMS server.
