programova obsluha paralerniho portu

[Ing. Peter Mihálik]

No pod NT som to neskusal, ale v helpe nikde nieje uvedene ze by to nemalo
chodit.

The DeviceIoControl function sends a control code directly to a specified
device driver, causing the corresponding device to perform the specified
operation.

A communications resource is a physical or logical device that provides a
single bidirectional, asynchronous data stream. Serial ports, parallel
ports, fax machines, and modems are examples of communications resources.
For each communications resource, there is a service provider, consisting of
a library or driver, that enables applications to access the resource.

A funkcia je dostupna ako pre W9x  tak aj pre Win NT.
Mozno potrebuje pre spolupracu este volanie inej funkcie, ktora umozni
pristup k portu.
Mozno ze to bude otazka administracie Win NT a bude potrebne nieco niekde
nastavit aby sa dana aplikacia dostala k portu.

Ako inac by bolo mozne vytvarat ovladace pre zariadenia, ktore sa pripojuju
na LPT ???
