I am doing a project using Mega2560, and need to use several serial ports. One of the serial port need a large TX buffer (e.g.128 bytes), but other serial port only need smaller TX buffer (e.g. 32 bytes). I know I can set the hardware TX buffer size in HardwareSerial.h to 128 bytes, but all 4 seri…
