C115 boot loader

Hi, I trying OsmocomBB on C115, I have a self build cable, already tested and working as explained in this message http://lists.osmocom.org/pipermail/baseband-devel/2011-August/002230.html I tried last version on git today, but with command osmocon I can't load firmware, it can't find the phone, I never receive "Received PROMPT1 from phone" I tried with -m c123xor and -m c123 without success same result. Short push on C115 not start the loader, so I press the power-on button normaly. Suggestions? Thank you Giovanni
