Ubuntu Serial Port Sniffer Cable

by

I am trying to connect minicom to a serial device that is connected via a USB-to-serial adapter. License mtkey vita scene prodad heroglyph 1. 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.

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 have to run as super user (i.e. Sudo minicom) • Sometimes I have to unplug and plug back in the USB-to-serial adapter to get minicom to connect to it.

IO Ninja is a scriptable terminal emulator, network sniffer, serial port monitor and an. Margulis moj drug luchshe vseh igraet blyuz noti dlya fortepiano. Monitors data flowing through a generic dual COM tap-cable — such as.

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. Long time reader, first time helper;) I'm going through the same hellish experience here with a Prolific USB Serial adapter and so far Linux is the easiest to get it to work.

On CentOS, I didn't need to install any drivers etc. That said, • dmesg grep -i tty or dmesg grep -i usb showed me /dev/ttyUSB0. • screen ttyUSB0 9600 didn't do the trick for me like it did in OSX • minicom is new to me but it was complaining about lack of /dev/modem However, this helped: So install minicom ( yum install minicom) then enter its settings ( minicom -s). Then select Serial Port Setup and change the Serial Device (Option A) to /dev/ttyUSB0, or whatever your device file is as it slightly differs per distro. Then change the Bps (Option E) to 9600 and the rest should be default (8N1 Y N) Save as default, then simply minicom and Bob's your uncle. 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. I did that and voila! Bottlerocket is able to communicate with my X-10 devices.

Though some might argue that Serial port are things in the past, it is still the most popular port for those who are into electronic DIY. Building electronic device with serial port interface is cheaper than buiding one that uses USB. That is the reason why people still sell USB-Serial adapter to those electronic DIY enthusiast. Here’s how to enable USB-Serial port adapter in Ubuntu Linux (with credit to from ) First plug in the USB-Serial Port adaptor to one of your USB port. Wait for a couple of second, then run “dmesg”. You should see these message at the end of dmesg output.
