Ubuntu/Linux 下使用UART console/terminal

Ubuntu/Linux 下使用UART console/terminal

1. 下載minicom
sudo apt-get install minicom

2. 設定minicom
sudo minicom -s

2.1. 修改Modem 的通訊設定(Serial port setup)，將Baund rate 設為 115200，資料位元設為 8，無同位元，停止位元設為 1 (Bps/Par/Bits：115200 8N1), 硬體Flow控制為off,
指定連接 Console的序列埠 (Serial Device)；其中/dev/ttyS0表示 COM1，/dev/ttyS1為 COM2、/dev/ttyUSB0為 USB to UART

2.2. 接著修改Modem 的撥接設定(Modem and dialing), 將Init string 和Reset string 都設為空白

2.3. 儲存設定(Save setup as df1)

Let some command without input password

1) execute visudo to edit the script of sudoer
sudo visudo

2) add below text in editor, hit ctrl-x and 'Y' to save it

touchscreen calibration

From: Tias 

There is now a generic touchscreen calibration utility that can 
calibrate evtouch, as well as evdev (the now preferred upstream driver 
for touchscreens) and others.

I've uploaded it to mentors and mailed:
http://lists.debian.org/debian-mentors/2010/08/msg00066.html

You can download a binary deb package on the website:
