Ubuntu 10.10中Usb轉串口的使用方法

首先，Ubuntu 10.10安裝minicom：sudo apt-get install minicom
在安裝好minicom之後對minicom進行配置，在此，需要注意的一點是在Linux環境下不許要裝Usb轉串口的驅動，在此，使用lsmod命令
linuxidc.com@ubuntu:~$ lsmod
Module Size Used by
pl2303 13696 0
usbserial 39507 1 pl2303
binfmt_misc 7984 1
可見，linux可以自動識別2303設備
之後在終端中輸入dmesg | grep usb命令
linuxidc.com@ubuntu:~$ dmesg | grep usb
[ 0.497563] usbcore: registered new interface driver usbfs
[ 0.497574] usbcore: registered new interface driver hub

[ 64.362942] usb 6-1: pl2303 converter now attached to ttyUSB0
[ 64.362970] usbcore: registered new interface driver pl2303
注意上面加紅的地方，他指明了設備號為：ttyUSB0
之後，就可以進行mimicom的配置了

在終端中輸入：minicom -s,選擇
+-----[configuration]------+
| Filenames and paths |
| File transfer protocols |
| Serial port setup |
| Modem and dialing |
| Screen and keyboard |
| Save setup as dfl |
| Save setup as.. |
| Exit |
| Exit from Minicom |
+--------------------------+
配置成如下方式：
+-----------------------------------------------------------------------+
| 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? |
+--------------------------------------------------------------------
完成後退出，退出後進入 Modem and dialing 配置成如下方式：
（原因：我們使用的是串口，而不Modem）
+--------------------[Modem and dialing parameter setup]---------------------+
| |
| A - Init string ......... |
| B - Reset string ........ |
| C - Dialing prefix #1.... ATDT |
| D - Dialing suffix #1.... ^M |

| |
| Change which setting? (Return or Esc to exit) |
+----------------------------------------------------------------------------+
配置完成後推出，在退出時一定要選擇Save setup as dfl
到此，Minicom的配置完成，連上串口線，打開開發板電源即可看到串口輸出的打印信息
