Hi everyone,

i managed to get hello_world working on my c121,
connected through a
pl2303 usb/serial cable to my macbookpro.
but found that the connection is extremely noisy.
often the movement of me putting down the phone on the table is enough
to break the upload.
is that a common problem with these headphone/serial cable plugs?
My question to the more experienced Calypso hackers (Harald?):
How reliable are your uploads, do they work at the first attempt all
the time, or should we expect some intermittent errors? How many?
I'm using a self-made cable consisting of a known good FT232R
converter @ 3.3V and a cut off headset cable (that also worked
flawlessly without any noise on another mobile phone before). My C123
also looks pristine. I manage to upload and run hello world
successfully in maybe one out of ten attempts, often have to remove
the battery because the phone just gets stuck. So I have ordered a new
cable from Akku-King as suggested on the Wiki.
