tu je problem... Ja ti mogu teoretski reci kako to rijesiti, a ti ako ne kuzis iz ovog sto cu ti napisati, obrati se Sljaki - on ce ti to moci bolje pojasniti...

copy/paste
Use standard cable with Tx Rx Gnd, but for MAX232 use V+ less than 5v.
Just try to reduse V+ to Max232 untill phone is connected and unlocked.
I have made a couple of tests and the V+ is between 3-4 v.
