Bipolar stepper motor sequence, wiring and dual h bridge
Please do improve the answer if you can as i really dont know much electronics .

However, I'm able to understand and get very good explanations and documentation from of-course THE WEB.

STEPPER MOTOR WIRING AND SEQUENCE
 WIRE TRACING WITH MULTIMETER
  This tutorial helped to trace coil/wiring using multimeter (that stupid to not even determine coil)

STEPPING SEQUENCE
 This very good demonstration helped alot to figuring out pulse sequence.

DUAL H BRIDGE
helpful documentation

PARALLEL PORT
Once i understand the above mentioned and able to create logic i use I/O in c/c++     outb();     to interface stepper motor.  

I need to study more to get control of speed and torque
