3.24.4 New Port Assignment

PF supports a set of drivers for a number of different boards and ports. To assign one of these to
a previously unassigned port number, execute the command with that port number. A message is
then printed to indicate that the port is unassigned and a prompt issued to request the type of
serial communication device. Pressing RETURN at this point lists the currently supported boards
and ports. Once the name of the board is entered, the port name is requested at the prompt. After
the port name is entered, PF prompts the user through the port configuration process.
Once a valid port is specified, default parameters are supplied. The base address of this new port
is one of these default parameters. Before entering the interactive configuration mode, the user is
allowed to change the port base address. Press RETURN to retain the present base address.
If the configuration of the new port is not fixed, then the system enters the interactive
configuration mode. Refer to paragraph 3.20.2 regarding configuring assigned ports. If the new
port has a fixed configuration, then PF issues the ''OK to proceed (Y/N)?'' prompt.
The user must enter the letter ''Y'' at the ''OK to proceed (Y/N)?'' prompt before PF initializes the
hardware. Pressing BREAK any time prior to this step or responding with the letter ''N'' at the
prompt leaves the port unassigned. This is only true of ports not previously assigned.
