My experience: I work under Windows with Cygwin so the OS internals
how the serial port is handled are (totally) different than Linux.
With the non-blocking variant of "osmocon" it was nearly impossible
to download the code to the phone in a reliable way. So I had to apply
an ugly hack to my version which basically switches the serial connection
to "blocking mode" during the download phase. This way it works rather
reliable here (regardless of using a "real" RS232 port or an USB to serial
So you might experience the same problem instead of a bad cable. You
can try the attached patch to "osmocom.c". The patch is not for the
latest GIT version, however it should be quite easy to apply it to
the current on. Again, its an ugly hack, but it works for me.
