Hello from Gregg C Levine
Perhaps you should start by posting for us, a description of your port
tester, and then the programs that you use. Further, a descriiption of how
your systen is configured, including lilo configuration, and modules
configuration. By what you've sent already, not many of us, can give you the
entire answer that you need. Especially since some lines on the port are
constantly active. They have to be, to monitor the printer, and the internal
databus for the computer. At least that was the case, many years earlier,
when I worked my way through testing ideas on a parport that was using
Qbasic as its programming language. And even Gwbasic.

Subject: [PARPORT] continuous parport activity??
> I post on the list because I find a strange activity on my parallel
> port. I've built a port tester with a few leds to watch the port
> activity in order to experiment a little bit with the parallel port.
> When I plug in the tester, I see a strange behaviour. Some of the lines
> are active intermittently. D4 and D7 seem to be high all the time.
> D0 is flickering with a high duty cycle. D1 and D2 blink at 1 or 2 Hz.
> D5 and D6 are low. D3 is ON and swith off some times to time.
> D1 and D2 seems to blink faster when I move my mouse.
> There is no file in the printer cue, I've tried to unload parport
> parport_pc and lp modules without success.
> I switched off cups and other services without more success.
> I use a Mandrake 9.1.
> Does any of you have an idea of what is going on with my parallel port?
> Thanks in advance.
