I planned to start with some guidance on how to recognize broken IOPSP code that needs to be reworked, and thought of giving you a list of members that should not be used, ever.

NET wrapper is thinnest.) That isnвЂ™t to say that all the bugs can be worked around, but if youвЂ™re lucky enough to have hardware that doesnвЂ™t trigger them, you can get IOPSP to work reliably in limited ways that cover most usage. (Unsurprisingly, these correspond to where the. There are some parts of IOPSP that are a lot less broken that the others, but that youвЂ™ll never find in MSDN samples. So, if you fall into one of these categories and using the Base Class Library is mandatory, you donвЂ™t have to suffer the worst of the nightmare. (This is not a good decision, the headaches IOPSP will cause in future maintenance far outweigh the effort of switching, and youвЂ™ll end up switching in the end to get around the unfixable bugs.) Or maybe you are responsible for improving IOPSP code that is already written, and the project decision-maker isnвЂ™t ready to switch horses.

The public license (as yet undetermined) might also present a problem for some users. NET Compact Framework (no support for mixed-mode assemblies)

Development policies that prohibit third-party projects.

Single-executable deployment (there may be workarounds involving ILMerge or using netmodules to link the C# code into the C++/CLI assembly).

Partial trust (not really a factor, since IOPSPвЂ™s Open method also demands UnmanagedCode permission).

The C++/CLI solution is incompatible with: But I realize that external circumstances sometimes prohibit using a C++/CLI mixed-mode assembly. NET event dispatch model, and multiple coworkers have expressed that itвЂ™s exactly how they want a serial-port class to work. NET engineers not only failed to devise a reasonable interface, they chose to disregard the WinAPI design which was very mature, nor did they learn from two decades of kernel team experience with serial ports.ДЄ future series of posts will present the design and implementation of a rational serial port interface built upon, and preserving the style of, the WinAPI serial port functions. NET doesnвЂ™t have a wrapper for, which notably includes device enumeration). NET, and still do when I want to use a function that.

WhatвЂ™s even more astonishing is that this level of failure occurred when the underlying kernel32.dll APIs are immensely better (IвЂ™ve used the WinAPI before working with. ThereвЂ™s no way to bypass or ignore failure of these settings during IOPSP initialization.) NET because IOPSP makes setting certain parameters mandatory, although they arenвЂ™t applicable to virtual ports, and closes the port on failure. (Plenty of evidence on StackOverflow attests to this, from devices that work in Hyperterminal but not. Nor could it have been tested in any real world scenario prior to shipping, without finding flaws that litter both the documented interface and the undocumented behavior and make reliable communication using System.IO.Ports.SerialPort (henceforth IOPSP) a real nightmare. They neither understood the characteristics of serial communication, nor common use cases, and it shows. To put it mildly, it was designed by computer scientists operating far outside their area of core competence. The System.IO.Ports.SerialPort class which ships with. NET Framework provide a rapid application development that is ideal for early development that needs to track changing requirements as hardware designs evolve.

Since looking at data through an in-circuit emulator debug interface is generally a miserable experience, getting serial data communication with a custom PC application is essential to analyzing data quality and providing feedback on hardware designs. Mostly USB virtual serial posts from FTDI, but also the USB Communication Device Class and real 16550-compatible UARTs on the PCI bus.

As an embedded developer who writes desktop software mostly for configuration of, and data download from, peripheral devices, I use serial data streams a lot.
