WebTo transmit a byte, the serial device driver program (running on the CPU) sends a byte to the serial port”s I/O address. This byte gets into a 1-byte “transmit shift register” in the serial port. From this shift register bits are taken from the byte one-by-one and sent out bit-by-bit on the serial line. Which is fastest port for data transfer?
