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/ttyS0 Press 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。 Welc +---------------------------------------------------------------+ | Minicom Command Summary | OPTIO | | Compi | Commands can be called by CTRL-A<key> | Port | | | Main Functions Other Functions | | | | Dialing directory.......D run script (Go).....G | Clear Screen... ....C | | Send files.................S Receive files.........R | cOnfigure Minicom..O | | comm Parameters....P Add linefeed.........A | Suspend minicom....J | | Capture on/off..........L Hangup.................H | eXit and reset.........X | | send break..............F initialize Modem....M | Quit with no reset. ..Q | | Terminal settings...T run Kermit..............K | Cursor key mode......I | | lineWrap on/off.......W local Echo on/off....E | Help screen.............Z | | Paste file.................Y | scroll Back...............B | | | | Select function or press Enter for none. | | | | Written by Miquel van Smoorenburg 1991-1995 | | Some additions by Jukka Lahtinen 1997-2000 | | i18n by Arnaldo Carvalho de Melo 1998 | +-------------------------------------------------------------------------------------+ 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:)
