Hello,

I have the problem connecting to the phone with osmocom tool. For what I
have read on this list trying to run helloworld example app should work, and
if there are problems connecting they stem from the cable/adapter being low
quality.
For now I have tried with three different usb-rs232 adapters (2 on
winchiphead ch341 chip then I switched to  prolific PL-2303 chip) and with 3
different phones (1xC155 and 2xC121) but in any of those configs I am not
able to successfully run helloworld - it doesn't receive 'prompt' message as
written in wiki - CompalRamLoader. Instead for C121 I always get:

./osmocon -p /dev/ttyUSB0 -m c123
../../target/firmware/board/compal_e88/hello_world.compalram.bin

I tried to stty different port speeds but still only got above sequence.
Have you got any suggestion what could be the problem or what direction
should I follow to get it working?
