Serial Port in Ubuntu - Using Terminal
We are often required to use Serial COM port in embedded system ( Like console booting in i.MX6). A USB to serial board comes handy in such case. First find out which Serial port corresponds to the hardware using
ls -la /dev/ttyUSB*
It is most likely going to be /dev/ttyUSB0
Next install putty
sudo apt-get install putty
Once it is install, you can launch putty using the following command
sudo putty /dev/ttyUSB0 -serial -sercfg 115200,8,n,1,N
This example assumes you want baud rate of 115200, 8 bit, no Parity
If you want to use the App instead, you will need to do following '
1. install gksudo
sudo apt-get install gksudo
gksudo is the gui compatriot of sudo
Next we need to modify the file /usr/share/applications/putty.desktop
Open /usr/share/applications/putty.desktop
sudo gedit /usr/share/applications/putty.desktop
Change the line
Exec=putty
to
Exec=gksudo -k -u root putty
