Turbo Pascal provides access to the I/O ports on the 80x86 CPU via two predefined arrays, Port and PortW, ali to ti funkcionise samo pod Windows-ima 9x i mozda Me, ali ne i kasnije, jer Window$ neda. Pise se otprilike ovako:

Const Data = $378;
Status = Data + 1;
Control = Data + 2;

var Bits: Byte;

Port[Data] := Bits; { output data }

Bits := Port[Status]; { input data }

Ima na netu gotovih resenja za direktnu komunikaciju sa ser/par portovima. Stvar je sto se mora napisati drajver. Neko je napravio univerzalni drajver koji radi i pod NT-om pa mu se obracas is Delphija...

Ne znam URL, davno sam to gledao...

Ja sam koristio sledece drajvere za NT:
