 + When connecting from another Linux, can use minicom 
 +<code>apt install minicom</code> 
 + 
 +Detect connection  
 +<code>ls /dev/tty*</code> 
 + 
 +For example, /dev/ttyUSB0 
 + 
 +Then connect to remote PC 
 +<code>minicom -b 115200 -D /dev/ttyUSB0</code> 
 +

 +== P.s ==

 +I prefer to use byobu as failsafe if have problems to exit minicom 
 + 
 +<code>apt install byobu</code>
