Should others have similar questions regarding SPC5 Studio components, please note the following:
For all SPC5 Studio components there is a doc folder.
For example, the Runtime IO component's documentation is located at: .\components\spc5_runtime_io_component_rla\doc The documentation can be found in: SPC5 Runtime IO RLA.chm The description of the Runtime IO component is described as: "What is Runtime IO Component? The Runtime IO Component allow you to use the standard printf function to write an output message.
As first implementation the stdout is redirect, throgh the freopen, to the serial device, in the future (when the support will be added) it can be redirect on CAN or Ethernet device. So to correctly initialize the serial driver, it needs to configure the Runtime IO component selecting the properly device to use, depending which platform we are using.
