Problem with osmocon (beginner)

[screaming-pain at libero.it]

Hi all,

I have been trying to load "hello world"  for hours with no joy so far :(
I am using Ubuntu Karmic and a motorola c115 my with a usb to serial and  mot 
T191 cable.
I tried different -m options, most of the times nothing happens, though if I 
play a bit with the earphone jack and the c115 start button
it seems some sort of communication starts and the each time I press the start 
button I can read the following 

got 1 bytes from modem, data looks like: 00  .
got 1 bytes from modem, data looks like: f1  .

what is going on? can anyone help me to understand how to proceed?

I got once during my trials the message:

Received PROMPT1 from phone, responding with CMD

but I had a wrong file name so it just wrote it could not find the file :(
I know I am a disaster but  I would appreciate if someone could give a hint

Thanks you very much,
Loretta
