Partial trust (not really a factor, since IOPSP’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 it’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.Ī 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 doesn’t have a wrapper for, which notably includes device enumeration). NET, and still do when I want to use a function that. What’s even more astonishing is that this level of failure occurred when the underlying kernel32.dll APIs are immensely better (I’ve used the WinAPI before working with. There’s no way to bypass or ignore failure of these settings during IOPSP initialization.) NET because IOPSP makes setting certain parameters mandatory, although they aren’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.
