How do I connect to TTY/COM (/dev/ttyUSB0)?
I am running Ubuntu for the first time by booting from a USB drive. Now I have plugged in a USB-to-serial converter which has been recognized and automatically added as
How do I access
Use one of screen's lesser known features:
if you need to specify the baud rate, add it after the serial device. eg, for 57600 baud: `screen /dev/ttyUSB0 57600`
Note that if you want to detach from the terminal and CTRL-D isn't cutting it, use CTRL-A then k to kill screen. I had to use this with the TTY at ~/Library/Containers/com.docker.docker/Data/com.docker.driver.amd64-linux/tty provided by Docker for Mac. CTRL-A then d will work too, but will leave your screen session running, which may or may not be what you want.
busybox microcom -t 5000 /dev/ttyUSB0
you can use ckermit also. It should be in the repository. After installing it create a file in your home directory called
.mykermrcthen add the 5 following lines:
set line /dev/ttyUSB0 set flow-control none set carrier-watch off set speed 115200 connect
parameters can be adjusted as necessary.
save the file.
to start it
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
You can use picocom, it is a minimal dumb-terminal emulation program. Basic usage is something like this (change 11520 to the desired baud rate):
$ picocom -b 115200 /dev/ttyUSB0
You have all the options you may want from a dumb-terminal program, like stop bits, parity, local echo, carriage return / line feed / backspace / delete / tab translation, X/Y/Z-modem and ASCII transfer integration, etc.
picocom --helpfor further information.
I was using puTTY to connect to the serial ports. But don't forget to add your user to dialout:
sudo adduser <username> dialoutthen reboot the system.
After that, you can use puTTY for serial connections such as
Needed Mint 17.1 to talk to my Arduino, after a little chasing around, it turns out that your user must be part of the
dialoutgroup to use the tty. This should apply to Ubuntu as well. You can do so either by running the command:
sudo usermod -a -G dialout username
Or graphically, by using:
Administration → Users & Groups → Manage Groups
In which case you would go to the line for
dialout, check the properties to ensure that
usernameis ticked, if not
usernamemust be added.
This worked for me and by the look of lots of posts others have had the same problem.
