The serial port communication programs <code>moserial</code> or <code>gtkterm</code> provide an easy way to check connectivity and modify <code>/dev/ttyUSB0</code> (or <code>/dev/ttyUSB1</code>!) settings. Even though there maybe only a single USB to RS232 adapter, the <code>n</code> designation <code>/dev/ttyUSBn</code> can and does change periodically! Both <code>moserial</code> and <code>gtkterm</code> will show what port designation is relevant in their respective pull down menus when selecting an appropriate <code>port</code> to use.

Check out <a href="https://help.ubuntu.com/community/Minicom" rel="noreferrer">help.ubuntu.com/community/Minicom</a> for details on <code>minicom</code>.

blocks|key|963290|text|首先，如果系统识别出您的适配器，请咨询dmesg+%7C+grep+tty。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。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|963291|别忘了用"Save+setup+as+dfl“将配置保存为默认值。它适用于我在VirtualBox上的Ubuntu11.04。|963292|entityMap^0|J|G|16|F|2D|C|0|0^^$0|@$1|2|3|4|5|6|7|J|8|@$9|K|A|L|B|C]|$9|M|A|N|B|C]|$9|O|A|P|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|Q|8|@]|D|@]|E|$]]|$1|H|3|-4|5|6|7|R|8|@]|D|@]|E|$]]]|I|$]]

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

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

blocks|key|963336|text|我遇到了完全相同的问题，并通过执行chmod+777+/dev/ttyUSB0修复了它。我再也没有遇到过这个错误，尽管以前让它工作的唯一方法是重新启动VM或拔下并重新插入USB转串行适配器。我在OS+X上运行Ubuntu+10.04+(Lucid+Lynx)+VM。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|963337|entityMap^0|H|M|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|K|8|@]|D|@]|E|$]]]|G|$]]

I had the exact same problem, and it was fixed by doing a <code>chmod 777 /dev/ttyUSB0</code>. I never had this error again, even though previously the only way to get it to work was to reboot the VM or unplug and replug the USB-to-serial adapter.

blocks|key|747689|text|每次插入转换器时，都需要设置权限。我使用PuTTY进行连接。为此，我创建了一个小Bash脚本来整理权限并启动PuTTY：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|747690|#!/bin/bash

You will need to set the permissions every time you plug the converter in.
I use <a href="http://en.wikipedia.org/wiki/PuTTY" rel="noreferrer">PuTTY</a> to connect. In order to do so, I have created a little Bash script to sort out the permissions and launch PuTTY:

<pre><code>#!/bin/bash
sudo chmod 666 /dev/ttyUSB0

putty
</code></pre>

P.S. I would never recommend that permissions are set to 777.

blocks|key|747762|text|我建议新手将PL2303连接到Ubuntu，chmod777+/dev/ttyUSB0+(文件权限)并连接到CuteCom串行终端。CuteCom用户界面简单直观。如果PL2303连续广播数据，则Cutecom将以十六进制格式显示数据|type|unstyled|depth|inlineStyleRanges|entityRanges|data|747763|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

I suggest that newbies connect a PL2303 to Ubuntu, chmod 777 /dev/ttyUSB0 (file-permissions) and connect to a CuteCom serial terminal. The CuteCom UI is simple \ intuitive. If the PL2303 is continuously broadcasting data, then Cutecom will display data in hex format

Putty on ubuntu
There is no need to install the driver for PL2303
So only type the command to enable the putty
Sudo chmod 666 /dev/ttyUSB0
Done
Open the putty.

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.

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

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

$ sudo lsusb -v

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

How do I connect to a terminal to a serial-to-USB device on Ubuntu 10.10 (Maverick Meerkat)?

我正在尝试将minicom连接到通过USB转串行适配器连接的串行设备。这是一个PL2303，从我所读到的一切来看，不需要额外的驱动程序。该设备被识别为PL2303。我是minicom的初学者。这是要执行的正确命令吗？或者我需要配置一些东西吗？$ sudo minicom --device /dev/ttyUSB0min...
