very useful tip for embedded Linux engineers and those who work with Linux Console using minicom or teraterm
normally if we type ps in serial console, it will show the process , if the length is more than 80 character(which is default) we cannot see the string after 80 characters in the consol,
with the below command you can adjust the width of the terminal with cols argument and number of rows using the  argument rows to the command stty
stty cols 160 rows 40 this can be used separate also stty cols 160 stty rows 50
Hope this help in ps and htop command when u run and other applications
