Original description
Am I correct in understanding the code from HardwareSerial.cpp allocates either 16 or 64 bytes (based on the size of RAM) for a ring buffer based on the existence of the UBRRxH register?
This seems presumptuous.
Perhaps the user better knows which USARTS he's using.
Could the code be revised to allow user defined symbols before inclusion of HardwareSerial.cpp to specify the USARTs to be used.
Similarly, perhaps the user might define SERIAL_BUFFER_SIZE (based on USART speed, F_CPU and application experience) to be used instead of the default.
While we're reducing RAM, should the head & tail be 8 bit.
