Summary
Serial ports and serial devices are two of the most important concepts of an embedded computer, but tons of other peripherals exist. You should try to modify the example programs in this chapter in order to fit your needs, or you can go directly to the upcoming sections where we'll introduce new devices.
You've seen how to set up the communication parameters from the command line or using the C or Python language, and you saw how to manage the data flow from the serial devices. Also, we took a look at the SLIP line discipline in order to establish an Ethernet-over-serial port communication.
In the next chapter, we will take a look at the USB that allows people to connect several kinds of electronic devices to a computer through the same port, for instance, a hard disk, a keyboard, or a serial device, as just seen in this chapter.
