hi all,
Currently I am using SUSE linux 8.1.
I am facing problem in serial port configuration in suse linux. I heard and saw the console like
SuSE invoke the setserial command by default when booting the system. How can i know wheather my serial port is configured properly or not.
The problem what i am facing is i am not getting any response from the external device.
if i type setserial command i am getting this message like
specuser@xddhutch:~> setserial -ga /dev/ttyS0
/dev/ttyS0, Line 0, UART: 16550A, Port: 0x03f8, IRQ: 4
Baud_base: 115200, close_delay: 50, divisor: 0
closing_wait: 3000
Flags: spd_normal skip_test
From linux planet i came to know like
" Another cause reported for the SuSE distribution is that there may be two serial drivers present instead
of one"
How can I know wheather two or one serial driver present.
One more thing they are suggesting like mouse can access the same port ie. what accessed by serial port.
How can i test these things.
Do u have any idea how to trouble shoot my serial port wheather it is properly configured or not
there isn't much to configure for serial ports since most of it (if not all) is done by the kernel (or at least Should be)
make sure you have serial support enabled in your kernel and that you have set sane permissions to the /dev/ttyS# devices (chmod 777 /dev/ttyS0 /dev/ttyS1, etc)
after that, you should be able to use them by simply telling your program to look into a particular device node
hi
thanks for you kind message but chmod 666 is not sufficient do u we need to execute permisson for owner group and others
expecting your kind reply
thanks
sincerely
