首先,将串口设备加入虚拟机中:setting->serial port->use physical port on the host->COM1->Finish
之后,查看Fedora中是否安装了minicom: rpm -qa|grep minicom,如果没有,那么:yum install minicom
安装成功之后对minicom进行设置:

安装好后,需要先对minicom进行配置,不能直接输入minicom,因为minicom运行时默认在/dev下有modem这个目录,而实际并没有,因此要修改默认的配置。一般第一次启动,需要使用命令minicom –s 对minicom进行配置,配置完成后,选择Save setup as df1,以后就可以直接使用minicom了。
(0)安装minicom,未配置前在终端中输入命令minicom,提示如:
#minicom
minicom: there is no global configuration file /etc/minirc.dfl
Ask your sysadmin to create on
e (with minicom -s).
(1)在root下,输入命令minicom –s,屏幕出现如下的界面:
# minicom -s
minicom: WARNING: configuration file not found, using defaults
+-----[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 |
+------------------------------+(2)设置serial port setup
使用down箭头选择serial port setup,出现具体各选项的配置:
+-----------------------------------------------------------------------+
| A - Serial Device : /dev/modem |
| B - Lockfile Location : /var/lock |
| C - Callin Program : |
| D - Callout Program : |
| E - Bps/Par/Bits : 115200 8N1 |
| F - Hardware Flow Control : Yes |
| G - Software Flow Control : No |
| |
| Change which setting? |
+-----------------------------------------------------------------------+
说明:
将选项A的值设置为/dev/ttyS0表示是串口1,如用串口2,设置为/dev/ttyS1,依次类推;
将选项E的值(波特率)设置为115200;
将选项F的值(硬件流)改成No;
设置过程中命令的使用,例如需要修改选项A的值,在Change with setting?选项后输入
A则光标转移到A选项后,可以对A选项的值进行修改。
修改完后的界面如下:
+---------------------------------------------------------------------+
| A - Serial Device : /dev/ttyS0 |
| 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? |
+----------------------------------------------------------------------+
按回车退回[configuration]界面。
(3)在[configuration]界面中,选择Save setup as dfl。
选择Save setup as dfl选项将修改后的配置信息进行保存为默认的配置选项。
(4)选择Exit from minicom 。
选择Exit from minicom 选项从配置菜单返回到命令行。
(5)重新启动minicom,则可以使用。出现的界面如下:
#minicom
Welcome to minicom 2.3
OPTIONS: I18n
Compiled on Feb 26 2009, 00:28:35.
Port /dev/ttyS0Press CTRL-A Z for help on special keys
附加说明:
minicom 启动后,先按 Ctrl+A 键,再按 Z 键(注意不是连续按,Ctrl+A松开后才按 Z) ,进入主配置界面。如按q可退回终端。

+-------------------------------------------------------------------------------------+串口转USB线在linux下使用
首先把usb转串口线插上然后用dmesg | grep usb查找如果看到:
“drivers/usb/serial/usb-serial.c: USB Serial support registered for Generic”
就说明设备已被识别,然后往下看
drivers/usb/serial/usb-serial.c: USB Serial support registered for PL-2303
usb 2-2: PL-2303 converter now attached to ttyUSB0 (or usb/tts/0 for devfs)
说明我的usb转串口芯片是PL-2303,对应系统设备是 dev/usb/tts/0,最后只需在minicom配置文件里将端口改成/dev/usb/tts/0就可以使用了:)
