如何在Ubuntu 10.10(Maverick Meerkat)上将终端连接到串行到USB设备? [英] How do I connect to a terminal to a serial-to-USB device on Ubuntu 10.10 (Maverick Meerkat)?

问题描述

我正在尝试将minicom连接到通过USB到串行适配器连接的串行设备.这是PL2303，从我读过的所有内容来看，不需要其他驱动程序.该设备被识别为PL2303.

I am trying to connect minicom to a serial device that is connected via a USB-to-serial adapter. This is a PL2303 and from everything I've read no additional drivers are required. The device is recognised as a PL2303.

我是minicom的初学者.这是执行正确的命令吗?还是我需要配置一些东西?

I'm a beginner at minicom. Is this the correct command to execute? Or do I need to configure something?

$ sudo minicom --device /dev/ttyUSB0
minicom: cannot open /dev/ttyUSB0: No such file or directory

$ sudo lsusb -v

Device Descriptor:
  bLength                18
  bDescriptorType         1

$ tail /var/log/syslog  #then removed and attached the device.

推荐答案

首先使用dmesg | grep tty检查系统是否识别您的适配器. 然后尝试使用sudo minicom -s运行minicom，转到串行端口设置"​​，并将第一行更改为/dev/ttyUSB0.

First check with dmesg | grep tty if system recognize your adapter. Then try to run minicom with sudo minicom -s, go to "Serial port setup" and change the first line to /dev/ttyUSB0.

不要忘记使用将设置另存为dfl"将配置保存为默认设置.它对我在VirtualBox上的Ubuntu 11.04上有效.

Don't forget to save config as default with "Save setup as dfl". It works for me on Ubuntu 11.04 on VirtualBox.
