Parallel ports
On a standard PC and some x86 systems, parallel ports use the devc-par driver; see
the BSP documentation for the driver for your target hardware.
By default, the driver detects the parallel port. If you need to, you can use the -p
option to specify the location of the parallel port.
If the driver fails to detect your parallel port, ensure that the port is enabled in the
BIOS. If that fails, try specifying the I/O port when you start the driver.
Terminals
On a standard PC and some x86 systems, the devc-con or devc-con-hid driver
controls the physical console, which consists of the display adapter, the screen, and the
system keyboard. By default, the driver is configured for up to four virtual consoles,
/dev/con1 .../dev/con4. The devc-con driver is also the keyboard driver for
non-USB keyboards in text mode. You can start the driver with this command:
devc-con &
The devc-con-hid manager is similar to devc-con, but works in conjunction with
io-hid and supports PS2, USB, and all other human-interface devices.
For more information, see devc-con and devc-con-hid in the Utilities Reference.
I/O attributes
To set or display the I/O attributes for a character device (tty), use the stty utility. For
more information about setting up your terminal, see “Terminal support” in Using the
Command Line.
Network adapters
The main steps in setting up a network adapter are:
• identifying your Network Interface Card (NIC)
• starting the driver
• making sure the driver and hardware communicate
Identify your NIC
The documentation for the hardware should describe the type of chipset used.
If you don’t know what type of chipset you’re using, you can identify it using pci
-vvv.
Find the entry for the Network controller and it’ll give you details on the
manufacturer/vendor ID and device ID. Either find the information on the
manufacturer’s website, or use the vendor ID and device ID to cross-reference it with
this online site:
