What is Second Asynchronous Interface for 80C51 about?

The document describes how to implement a second asynchronous serial interface on an 80C51 microcontroller family using only the existing hardware. It utilizes the Timer 1 interrupt to sample the receive pin and generate the transmit pin signal. The implementation requires no additional hardware, uses no extra timers, and allows full duplex communication with different baud rates for receive and transmit. Software routines are provided for installing the interface and transmitting/receiving characters using
