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?

Provide your sudo password and the serial terminal GUI will appear. Click 'Configuration' and select 'Port', as shown in the figure below. In the pop-up window browse to the USB TTY port as shown in the figure below. Set the speed, bits and party and start working/playing.

1. How do I check and configure serial ports under Linux for various purposes such as modem, connecting null modems or connect a dumb terminal? Linux offers various tools. Linux uses ttySx for a serial port device name. For example, COM1 (DOS/Windows name) is ttyS0, COM2 is ttyS1 and so on.
2. Apr 09, 2019  There are two other articles on a serial port adapter for Windows.Below is the instructions for Linux and how to connect your serial adapter while using Linux. This should work for most people using Linux and a serial adapter or usb to rs232 driver which is being discussed.

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.

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

You will need to set the permissions every time you plug the converter in.I use PuTTY to connect. In order to do so, I have created a little Bash script to sort out the permissions and launch PuTTY:

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

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

Check out help.ubuntu.com/community/Minicom for details on minicom.

I had fix this with adduser *username* dialout. I never had this error again, even though previously the only way to get it to work was to reboot the PC or unplug and replug the usb to serial adapter.

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

Linux Usb To Serial Tty

However, this helped: https://www.centos.org/forums/viewtopic.php?t=21271

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.

HTH.

I get get the same minicom error, 'cannot open /dev/ttyUSB0: No such file or directory'

Three notes:

1. 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.

2. I have to run as super user (i.e. sudo minicom)

3. Sometimes I have to unplug and plug back in the USB-to-serial adapter to get minicom to connect to it.

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.

Usb To Serial Driver Windows 10

I had the exact same problem, and it was fixed by doing a chmod 777 /dev/ttyUSB0. 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. I am running Ubuntu 10.04 (Lucid Lynx) VM on OS X.

Peter Mortensen

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

Linux Usb To Serial Adapter Driver

I just got my GUC232A cable with a molded-in PL2302 converter chip. Swords and sandals 3 full game.

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-10devices.

I was tasked with writing some code for a PTZ-head using the Pelco-D protocol, which uses RS485 (2-wire).The code is intended to run on a Raspi, so I first figured out how to get that going. Once I was satisfied that I could exchange data between the Pi and the PTZ, I sat down at my laptop to write some actual code and hooked the PTZ up to it via the Ex-1333V usb to serial adapter which we aquired for this purpose. It can do RS232, 422 and 485. It apeared to work well enough with just the standard Ubuntu drivers, at least both its ports were properly recognised.

But I was unable to send data to the head. The transfer indicator on the adaptor lit up, but the head didn't move. For diagnosis, I connected my laptop to the Pi instead. Again the indicator lit up, but the pi didn't receive anything. So I tried the other way around, sending from the Pi and receiving on the laptop. That worked without issue.I started to fiddle around with configuration, and eventually realised that the pi was getting a signal when the adapter was set to RS232. The data was garbled, of course, but at least something was getting through.

Linux Usb To Serial

So I started thinking about that driver CD provided with the adapter. Might be the driver converts the data before sending it through the USB, instead of converting it on the adapter? This would of course not be handled by the standard drivers. That's the assumption I'm working under currently in any case.

So I got the linux drivers on the cd, which turned out to be a tar containing a c-file, a header file and a makefile. I'm not very familiar with low-level linux stuff, so I was a bit confused. Sure, I could build it, but then what?Turning to the adapters poor excuse for a manual, the only thing I could find was the nice suggestion to 'please follow the instructions for installing USB port drivers on your particular linux distribution'. So I went looking for that, and found.. nothing.

Which brings me here. I'll freely admit that this is the first time I'm working with serial, so there might be other things I'm not understanding here, and you should free to point them out. But for the moment I think those drivers are my best bet, so could somebody explain to me how to install them?

ADDENDUM:

I wrote above that I assumed I could build the C project easily enough, but I didn't actually try. Saw no point in it without knowing what to do afterwards. I assumed wrong it turns out, as building produces an error. Here's the make output:

I've googled for the error, but couldn't quite pin down what to do. Apparently there should be a symlink to some system headers in this place, but isn't, but I can't figure out what header the link should point to exactly.If I interpret the makefile right (really not familiar with makefile, never went beyond 'make this-project-i-downloaded', which usually worked), it's just attempting to build an object (.o) file:

There's also a rather long rules file, but I doubt it will help a lot if I post the whole thing. It seems to be taken and modified from a book, as per its header:

So maybe somebody already knows how it looks.
