[OBD II] Help me Please

Dears,
IS IT POSSIBLE TO ESTABLISH

DIRECT COMMUNICATION BETWEEN THE DIAGNOSTICS SOFTWARE

AND THE VEHICLE´S COMPUTER

WITHOUT HAVING AN ELECTRONICAL INTERFACE BETWEEN THEM TWO (THAT IS: BETWEENTHE SOFTWARE FOR DIAGNOSIS AND THE VEHICLE?)

REMARK: NAMING THE ELECTRONICAL DEVICES AS ELECTRONICAL INTERFACE, SUCH AS:

Andy Whittaker's OBD-II ISO9141 interface:

http://www.andywhittaker.com/ecu/obdii_hardware.htm

Jeff's OBD-II ISO 9141 interface:

http://www.planetfall.com/~jeff/obdii

Silicon Engines ISO 9141 interface:

http://www.siliconengines-ltd.com/products/se/9141/9141.html

B.Roadman ISO9141/VPW/PWM interface:

http://obddiagnostics.com/

Multiplex Engineering VPW, PWM, and ISO 9141-2 interface:

http://www.multiplex-engineering.com/products.htm

WHAT FUNCTION OR FUNCTIONS ARE ACCOMPLISHED BY THE ELECTRONICAL INTERFACE?

COULD THE ELECTRONICAL INTERFACE FUNCTIONS BE ACCOMPLISHED THROUGH THE SOFTWARE?

Thanks
