Im facing some issues to figure out sequence of my bipolar(specifically) and unipolar stepper motor. However , I've managed to get Dual H Bridge but couldn't find out the example/documentation for the one i got.

I want to drive my bipolar stepper motor via dual h bridge using parallel port and unipolar via IC UN2003.

You're expert guidennce for pulse sequence and wiring identification will be truly appriciable. Thanks!!

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
