Console Port
Driver
The fields of the console port drivers driver descriptor are the
same as the console class drivers driver descriptor, with one
exception: the port driver contains pointers to the console port
level routines. The port driver supports all functions whether
or not the device supports console output only or console input
/output. Figure 2–12 shows the function block of the port driver.
