The commands needed to control a 16550 UART are much different from the commands needed to control an FTDI serial port converter, but each hardware-specific device driver abstracts these details into This is easy to do with a simple program that runs through all possible combinations of different values for the three port pins and then sends the value to the device. In addition, the driver's configure interface performs one-time initializations when called by the boot software or by the sysconfig utility. Figure 1-1: When the Kernel Calls a Device Driver Some
