To: Linux to use USB to the serial line of the method-minicom and hl-340/341 (USB switch serial line) drive __linux

Installation Configuration minicom
--------------------------------------------------
# lsmod | grep usbserial(If you use the serial port directly, but do not use USB to switch serial device, this step can be skipped)
If there is usbserial, the system supports USB to the serial port.

Install minicom (fedora comes with minicom, this step can be skipped)
apt-get Install minicom
apt-get Install Lrzsz
Configure Minicom
# minicom-s
Serial Port Setup[Enter]
+-------------------------------------------------------------+
| A-serial Device: /dev/ttyusb0|
| B-lockfile Location:/var/lock |
| C-callin Program: |
| D-callout Program-: |
| E-bps/par/bits: 115200 8N1|
| F-hardware Flow Control:no |
| G-software Flow Control:no |

|                                    Change which setting? |
+-------------------------------------------------------------+
Note: If you do not use a USB dongle, serial device is configured to /DEV/TTYS0

Save Setup as DFL
Exit from Minicom




transferring files using minicom
--------------------------------------------------
# minicom
(Ctrl + a)--> s--> zmodem--> [Okay]-->

+-----------------------------------------+
| No file selected-enter FileName: |
|>/home/zxl/ssl/codes/led/lls_led.ko | [Enter]
+-----------------------------------------+






Note: Download kernel by minicom in Ubuntu
--------------------------------------------------
When I download the Linux kernel by x protocol in minicom, it says "failure executing, the Press any key to protocol".
The problem is the "x protocol isn ' t installed bye Ubuntu by default and so for should install it by hand:
# apt-get Install Lrzsz
After the successful download and install, you can send the files by the X protocol in minicom.
LrzszIncluding the X/y/zmodem protocol.




Install Lrzsz
--------------------------------------------------
1. Download lrzsz-0.12.20.tar.gz from the website below
Http://www.filewatcher.com/m/lrzsz-0.12.20.tar.gz.280938.0.0.html

2. Tar zxvf lrzsz-0.12.20.tar.gz
3. Look inside the install documentation for installation parameter descriptions and details
4. # CD lrzsz-0.12.20
5. #./configure--prefix=/usr/local/lrzsz
6. # Make
7. # make Install
8. Establish Soft Links
# Cd/usr/bin
# ln-s/usr/local/lrzsz/bin/lrz RZ
# ln-s/usr/local/lrzsz/bin/lsz sz
So minicom can use Zmodem to transfer files.

B-upload Directory:/tmp
The PC sends files to the Development Board and needs to send the files in the/tmp directory (the directory on the PC). Once this configuration is done, each time you send a file to the Development Board, you can simply enter a file name without having to enter the absolute path of the directory where the file is located


Development Board---> PC
