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

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.

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.

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

You can use putty. Its an ssh/serial/telnet client for Windows and Linux. You can download it from http://linux.softpedia.com/get/System/Networking/PuTTY-347.shtml
