If you are allowed to access I/O ports directly isn't a language, but
an operating system issue. Any decent OS, in particular a multitasking
one, must protect itself and its users from misbehaved programs.

>From your answer to Gerrit I presume you want to control a serial
port. If you're running on *nix, use /dev/ttyS* and look into the
termios(+TERMIOS) module for setting up serial parameters. I don't
care enough about Win?? to know their way.

btw Gerrit: even with your own interpretation RTFM stays bad style.
