I am trying to connect minicom to a serial device that is connected via a USB-to-serial adapter. Install Php Curl Extension Centos 7. 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? $ sudo minicom --device /dev/ttyUSB0 minicom: cannot open /dev/ttyUSB0: No such file or directory $ sudo lsusb -v Bus 002 Device 006: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial Port Device Descriptor: bLength 18 bDescriptorType 1 $ tail /var/log/syslog #then removed and attached the device.

By default Linux will grab the serial port and use it as a terminal. If you want to use it for other purposes you must prevent this. Here are the methods you can use. This class can be used to communicate with a serial port under Linux or Windows. It takes the path (like '/dev/ttyS0' for linux or 'COM1' for windows) of serial device and checks whether it is valid before opening a connection to it. Once the connection is opened, it can send data to the serial port, and read answers (reading is only implemented for Linux).

I get get the same minicom error, 'cannot open /dev/ttyUSB0: No such file or directory' Three notes: • I get the error when the device attached to the serial port end of my Prolific Technology PL2303 USB/Serial adapter is turned off. After turning on the device (an embedded controller running Linux) minicom connected fine.

I am running Ubuntu 10.04 LTS (Lucid Lynx) under VMware (running on Windows 7). In this situation, make sure the device is attached to VM operating system by right clicking on the USB/Serial USB icon in the lower right of the VMware window and select Connect (Disconnect from Host).

Remember to press Ctrl + A to get minicom's prompt, and type X to exit the program. Just exiting the terminal session running minicom will leave the process running. I just got my GUC232A cable with a molded-in PL2302 converter chip. In addition to adding myself and br to group dialout, I found this helpful tip in the README.Debian file in /usr/share/doc/bottlerocket: This package uses debconf to configure the /dev/firecracker symlink, should you need to change the symlink in the future run this command: dpkg-reconfigure -pmedium bottlerocket That will then prompt you for your new serial port and modify the symlink. This is required for proper use of bottlerocket.
