= Debug on windows =

Install usb2uart adapter's driver. Connect adapter to PC , you will find COM port like :

Putty is very populate tool on Windows. [https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html Download putty here.]

Run PUTTY.exe, select Connection type of "Serial" , input COM port found in Device Manager.

Then Click "Open" to start debug console.

 

= Debug on Ubuntu =

"Kermit" and "MiniCom" are very famous tools on Ubuntu.

 Connect adapter to PC , find COM port :
<pre>$ ls /dev/ttyUSB*
/dev/ttyUSB0
</pre>

 

 

== Kermit ==

'''Install Kermit : '''
<pre>sudo apt-get update
sudo apt-get install ckermit
</pre>

'''Config Kermit : '''
<pre>vi $HOME/.kermrc;
</pre>

Input the following content : 
<pre>set line /dev/ttyUSB0
set speed 115200
set carrier-watch off
set handshake none
set flow-control none
robust
set file type bin
set file name lit
set rec  pack 1000
set send pack 1000
set window 5

</pre>

'''Note : '''

Change "/dev/ttyUSB0" according your system, Use Command "ls /dev/ttyUSB*" .

'''Run kermit'''
<pre>sudo kermit
</pre>

 

= MiniCom =

'''Install MiniCom: '''
<pre>sudo apt-get update
sudo apt-get install minicom
</pre>

 

'''Run MiniCom'''
<pre>$ sudo minicom

+ROM-6881 can communicate with a host server using serial cables. Common serial<br/> communication programs such as HyperTerminal, Tera Term, or PuTTY can be used<br/> in this case. The example below describes the serial terminal setup using HyperTerminal<br/> on a Windows host:<br/> 1. Connect ROM-6881 with your PC using a serial cable.<br/> 2. Open HyperTerminal on your Windows PC, and select the settings demonstrated<br/> in the photo below.<br/> 3. Insert power adapter to DC jack and power up the board. The Debug console<br/> log will be displayed on the terminal screen.
