Hi, I would like to know if there are any difference between I/O ports such as serial port, parallel port, keyboard and ide from those ones used by network interface, such as ssh, ftp, http and telnet. Both can be accessed by check_region(), request_region() and release_region() functions? If not, what functions can be used to access those ports in kernel mode?
