During these early phases, the bootloader often gives information over the serial port and can respond to its own set of commands. Typically, a router first starts its вЂњpermanentвЂќ bootloader which is responsible for the first steps of finding the OpenWrt firmware and starting OpenWrt running. Most routers come with an UART integrated into the System-on-chip and its pins are routed on the Printed Circuit Board (PCB) to allow debugging, firmware replacement or serial device connection (like modems). If one wishes a more permanent installation, mechanical skills in modifying the case may also be needed. The cost of components is relatively low a 10-euro/dollar project if one uses вЂњeBay-gradeвЂќ parts (which are likely sufficient). Console access to the bootloader will often allow one to fetch and flash new firmware and may be the only way to do so on some routers if the firmware is not functional.Д®nabling a serial port, if there is not one already available on the case, typically involves opening the case and basic soldering skills.

A console to the running system will let you correct a misconfigured network, for example. These serial ports typically provide a console to the bootloader and, when the firmware has booted, a console to the running system. Most devices supported by OpenWrt have or can be modified to have a serial port. However, some bootloaders don't have a вЂњreally failsafeвЂќ network re-flash feature, making a serial console one of the few ways to recover from a вЂњbad flashвЂќ or an error in a user's own configuration. 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.Most people get along without a serial console for their device because they're able to flash a working firmware the first time - or are able to apply various recovery methods - and do all their communicating with the device over a network. 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'?Дoes 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.
