1.	Which of the following is the first flow control method?(a) software handshaking(b) hardware handshaking(c) UART(d) SPIThe question was posed to me during an online exam.This is a very interesting question from Asynchronous Flow Control topic in chapter Basic Peripherals of Embedded Systems
Answer» Correct answer is (b) hardware handshaking Explanation: The FIRST FLOW control method is the hardware handshaking in which the hardware in the UART detects the POTENTIAL overrun and it will ASSERT a handshake line to tell the other UART to stop the transmission.
