RS232 / tty testing and simulation on Linux

( UPDATED 2022/02  - Use Docklight V2.4 and additional winetricks) Summary / TL;DR How to run Docklight on your Linux desktop without using VirtualBox/Windows ?  Use  WineHQ package and winetricks !  We successfully tested the access and use of serial ports (tty) and networking (TCP / UDP) functions, but display output is significantly slower than on VirtualBox .  For installation, use a 32-bit WINEPREFIX and  winetricks  corefonts consolas vb6run richtx32 comdlg32ocx comctl32ocx wsh57 . Experimental use only “Use at own risk” - The below description of Docklight installation and use on Linux desktop computers is for experimental use. It is currently not recommended in production environments. Limitations / Known issues -  For tty / serial ports, use Docklight V2.4 versions (e.g. the  Docklight Scripting V2.4 Preview ), not V2.3. Docklight Tap Pro and Docklight Tap 485 cannot be accessed.  In Docklight Scripting, some VBScript sys...

Out with D-Sub DB9 RS232 – In comes Ethernet, Wifi, Bluetooth, USB

For industrial measurement equipment, the classic serial RS232 DB9 or SUB D9 interface is still very much alive. In most cases because this was the original design. And all the device has to do, now and forever, is to pass a few measurements and respond to a few basic commands. However, in a world where RS232 DB9 connectors for PCs almost always come as external USB-to-RS232 adapters, and tablet computers with Wi-Fi and Bluetooth are becoming increasingly popular for operating panels, this does not really make sense any more. This is why equipment makers are gradually updating their connectivity, many times keeping their application layer serial protocol, but providing a modernized transport layer and physical connector to the end users. Popular solutions include: USB connector with integrated RS232-to-USB UART, e.g. using FTDI or Prolific chipsets and boards. Embedded Serial Device Server for TCP/IP via Ethernet or Wifi, e.g. Lantronix XPort or MOXA device server modules. ...
