Apr 09, 2019 USB-Serial Port adapter (RS-232) in Ubuntu Linux. Tracey Brown April 9, 2019 USB to Serial. 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.
May 12, 2008 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 Continue reading 'How to enable USB-Serial Port adapter (RS-232) in.

Apr 06, 2017 If I plug out & plug in cable into USB port, again it start sending data correctly. USB port /dev/ttyUSB0 don't send any packet. But if I plug out & Plug into USB 3.0, it start sending data packets. I used gtkterm to open /dev/ttyUSB0 to check the data packets. Look like USB driver have an issue with Ubuntu 16.0.4 with USB 3.0?

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.

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.

The real power and ease of using Web PI to install WordPress, PHP, and MySQL is evident after you choose WordPress and Click Install. Now thanks to Web PI with just a few clicks of your mouse you can have WordPress, PHP, and MySQL installed on Windows Server 2012 R2 in a few short minutes.rnrn Setting up Your SiternOn my test server I have a new installation of Windows Server 2012 R2 with IIS 8. This page is automatically created for the default site when you install IIS. Install wordpress on windows server 2012 r. Using the default site you’ll see the familiar IIS 8 welcome page called IISStart.htm. Be sure to delete it once you deploy your files.rnrnrnrn Launching Web Platform InstallerrnAfter installing the IIS role on your server you’ll be able to launch Web PI directly from IIS Manager by clicking on Get New Web Platform Components.

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?

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.
