The queues are used to tell when to turn off the interrupt for the transmit queue and turn it back one as well as when to return from the transmitting to the main program. Conclusion This lab was very effective in explaining how interrupts work. By building upon the material and code from the week before the ins and outs of interrupts are easily demonstrated. The importance of disabling the transmit interrupts when handling a receive interrupt is clearly demonstrated as well as why it is important to wait until the transmit interrupts are all handled before returning to the main program to reduce the loss of data being printed to the screen. It also shows clearly how the program works through the testing because it prints out the last character that you typed to the screen.
