Enables multiple serial ports to share the same semaphore. Doing so prevents more than one driver from using more than one of the serial ports in the group at a time; thereby preventing two drivers on different serial ports connected to different radios sharing the same frequency from colliding.
To allow serial ports to share the same semaphore, set SerialShareSemaphore to "1" (the default is "0"). The result is that all serial ports with the same Area parameter will use the same semaphore.
Default: SerialShareSemaphore = 0
