T3.2 Hardware Serial RX buffer size change

[MUIuser]

Hi all,
just cheched the Forum and Google but I did not found an answer.
I need to increase the RX buffer of hardwarewserial e.g. hardwareserial3 to 128 or 256 byte.
Standard seems to be just 64 - at least in my environment ... !?
I do not find any buffer size entry possibility in the .h or .cpp files?

Have anybody of you a solution/hint for me?
Thanks
Klaus

In :: ...\hardware\teensy\avr\cores\teensy3\serial3.c

look for >> #define SERIAL3_RX_BUFFER_SIZE 64 // number of incoming bytes to buffer

On Teensy 3.2 best to use Serial1 or Serial2 as they are backed by an 8 byte FIFO to help transfer integrity with fewer interrupts. Serial3 works of course - but at high baud rates it will be more overhead.
