    Description

      Commit qtserialport/28fe4bf781ac20cb4fcb39de81b9d76cd100ea5d introduced the emulation of Space/Mark parity on UNIX systems that do not define CMSPAR.
      Back then both read and write emulation was implemented.

      However, the read emulation was dropped over time. This leads to incorrect results while reading the data with Mark/Space parity enabled.

      The scope of this task is to investigate why the read emulation was dropped and to decide if it makes sense to reintroduce it.
