Unwanted RTS and DTR toggling while connecting to the port

[Kepsz]

Hi,

I just ran into a problem where a microcontroller gets rebooted because of the RTS and DTR signal togling while synaser is connecting to the microcontroller's serial port. The RTS and DTR signals are used to access the bootloader of the microcontroller. This issue and the solution was described here by someone else: https://forum.lazarus.freepascal.org/index.php?topic=63101.0

The mentioned solution does worked for me too.

The problem with the mentioned solution is that it can only be applied at system level, affecting all projects that uses synaser. So an option to change how the dcb.Flags handled in synaser.pas would be good.
