It also allows the use of named pipe technology to connect the created port to a serial application. Our freeware virtual serial port tools kit allows you to create virtual COM ports and connect them into pairs using software-based virtual null-modem cables. To me at least, it's quite overwhelming to understand and it's includes, then where these are being P/Invoked in mono, then translate it into CoreFX style shims and filter out unsupported platforms before begin to implement the C# mechanics. Free Virtual Serial Ports is a software COM port emulation utility for Windows platform. If we can lay down a checklist-y plan, based on your previous shim-driven API implementation experiences, that may lead to a successful implementation of Serial Port on Unix in near future. Should we ask contributors of and/or someone familiar with CoreFX shims can help moving the implementation any suggestions on 'where to start'?ĭoes it require all-in-one-go kind of scary PR, or else what would be the best logical division of this work into smaller chunks implementable one at a time (like port discovery, port opening, port closing, sending message etc.)? The significance of SerialPort has been established, there are some serious (even industrial) workloads which require serial communication and consider it as a main factor in choosing platform. I think we should port the System.IO.Ports native shim code from MonoPosixHelper into either a new shim library, or an existing shim library in dotnet/corefx. I think we would follow the same pattern here.

For code inside of the BCL, we have our own set of 'shim' libraries ( System.Native,, System.IO.Compression.Native, etc.) when we need to call into native libraries. is intended for code outside of the BCL that needs to call POSIX APIs. I don't think it is the plan to have CoreFX depend on, at least it was never my intention. are you aware of other cases where we might want to take a dependency from CoreFX onto Mono.Posix? I believe you had ideas for other Unix libraries we could offer, and those presumably would sit on Mono.Posix. That is certainly possible but it will require work and we will need to think twice before taking that dependency. We cannot depend on that package unless we pull the building of it into our closure for our build from source efforts. I assume it is fine for CoreFX code to depend on package although I don't know of precedent for an outgoing Nuget dependency.
