Dear Sir,
I have connected one of the data pins of the parallel port to control a relay.
The relay goes ON and OFF while system resets.
How can i avoid this.Any solution from you will be appreciated.
Thankyou

Dear Sir,
Also today i noted my parallel port clicks when the system shuts down.

Use a latch such as a 74HCT374 to enable the outputs and latch the data.
