 SCO comp.unix.sco.programmer FAQ. : Hardware related programming :
How can I directly read or write the parallel port to use it for input or to control my non-printer devices? |
| With the SCO provided drivers through and including OpenServer
5.0.4 family, you cannot directly manipulate or read the bits
in the printer port. You can communicate with custom equipment
by providing your own device driver.
This functionality is believed to exist in the Linux parallel port driver, so you could perhaps port that driver or at least use it as a starting place. | |
