Hi,
I found N900 could not be powered on by atgen driver due to baud rate problem.
If I add 'Baud=115200' into modem.conf, everything is fine. In gatchat/gattty.c,
the default baud rate is B0 which looks not correct, so I wonder whether we
should set the default baud rate to some values like minicom does.
My proposed fix was attached.
Regards,
Zhenhua

Hi Zhenhua,
Hi,
I found N900 could not be powered on by atgen driver due to baud rate
problem. If I add 'Baud=115200' into modem.conf, everything is fine. In
gatchat/gattty.c, the default baud rate is B0 which looks not correct, so
gattty code sets the serial port into raw mode if no options are given. These
days it is hard to find a real serial port device that actually needs the
options setup properly. Most simply work in raw mode.
I wonder whether we should set the default baud rate to some values
like
minicom does.
My proposed fix was attached.
The fix should really be inside atgen.c, as it logically belongs there. You
can make atgen use 'sane' defaults for true serial devices, but then you need
to add capability to put the modem into 'raw' mode.
