Kako preverim če kaka naprava zaseda Parallelni port PC?

Kako preverim če kaka naprava zaseda Parallelni port PC?

pr2501 ::

Spodnja zadeva je iz navodil za uporabo hardwearja za programiranje PIC mikrokontrolerja. Navaja da je lahko krivo za določeno opozorilo zasedanje porta s strani neke naprave. Torej kako preverim, kaj zaseda paralelni port?


Programming fails, and WinPic says "WARNING: Windows fooled around with the LPT port bits". What does that mean ?
This message means, that -for some strange reason- windows has reprogrammed one of the control registers of the serious ports. WinPic checks from time to time, if a value it has written into a certain register is still in there. If the register value seems to have changed by mysterious ways, it shows the warning mentioned above. The reason is usually some kind of driver which lurks in the background (of the windows driver system), and watches the parallel port. If "something" happens on the port, it tries to talk to a printer, a scanner, or whatever is usually connected to that port. So what to do:
make sure no printer driver, or scanner driver, etc, has occupied this port (though WinPic usually works even though a printer driver occupies the port !). I got a report from a user of Windows 2003 that on his system, the culprit was a scanner driver, and after shutting that thing down the strange error messages from WinPic disappeared.

Mogoče PortMon ali nek lpt viewer.

To je tudi mene zafrkavalo sicer pri programiranju Atmel-a. Torej inštaliral sem si programček UserPort (http://hem.passagen.se/tomasf/UserPort/) in v programi vpisal pod Enter grand interval 0x000-0x3FF. Klikni Add, potem klikni start in program zapri. Ni potrebno vsakično ponovno odpiranje programa. Kar še naredi je, da v mapo windows\system32 prilepiš datoteko UserPort.sys
(meni deluje na win2000/32b, winXP/32b, win7/32b).

Hvala.
Je trepa skopirati v mapo mapo windows\system32\driver.

Ampak mi ne deluje, oz. ne pomaga. Imam XP profesional.

Bom po službi probal še lpt viewer.

UserPort na Windows 2000 deluje.
lpt viewer moram pobrati še dol in isprobati za XP.
