 ## Common interface

+This interface is declared in `Marlin/src/core/serial_base.h`
 Any implementation will need to follow this interface for being used transparently in Marlin's codebase.
 
 The implementation was written to prioritize performance over abstraction, so the base interface is not using virtual inheritance to avoid the cost of virtual dispatching while calling methods.
 Instead, the Curiously Recurring Template Pattern (**CRTP**) is used so that, upon compilation, the interface abstraction does not incur a performance cost.
 
-Because some platform do not follow the same interface, the missing method in the actual low-level implementation are detected via SFINAE and a wrapper is generated when such method are missing. See `CALL_IF_EXISTS` macro in `Marlin/src/core/macros.h` for the documentation of this technic.

 2. `ForwardSerial` is a composing wrapper. It references an actual Arduino compatible `Serial` instance. You'll use this if the instance is declared in the platform's framework and is being referred directly in the framework. This is not as efficient as the `BaseSerial` implementation since static dereferencing is done for each method call (it'll still be faster than virtual dispatching)
 3. `ConditionalSerial` is working a bit like the `ForwardSerial` interface, but it checks a boolean condition before calling the referenced instance. You'll use it when the serial output can be switch off at runtime, for example in a *telnet* like serial output that should not emit any packet if no client is connected.
 4. `RuntimeSerial` is providing a runtime-modifiable hooking method for its `write` and `msgDone` method. You'll use it if you need to capture the serial output of Marlin, for example to display the G-Code parser's output on a GUI interface. The hooking interface is setup via the `setHook` method.
-5. `MultiSerial` is a runtime modifiable serial output multiplexer. It can output (*respectively input*) to 2 different interface based on a port *mask*. You'll use this if you need to output the same serial stream to multiple port. You can plug a `MultiSerial` to itself to duplicate to more than 2 ports.
