Hi, I can't use the "cu" command to open a terminal on the serial port "ttyS0". When I type (login as "root" of course): cu --parity=none --line /dev/ttyS0 --speed 9600 I always have the error message: cu: open (/dev/ttyS0): Permission denied cu: /dev/ttyS0: Line in use -> The permission of the file "/dev/ttyS0" are correct (I have checked it - and I am root). -> when I type "ps -x" I don't see anything related to "/dev/ttyS0". -> I have deleted "/dev/ttyS0" and then recreate it with the "mknod" command (mknod /dev/ttyS0 c 4 64), but it doen't do anything. -> I have used "stty" to set up the speed, ... -> the serial port is working because I can make a "wcho" into it (echo "toto" > /dev/ttyS0) and see the output on a externel console connected to the serial port. -> I can also "read" the serial port (more /dev/ttyS0. -> I have read the serial-HOWTO. Does somebody have any idea ? Thank you very much for your help. PS: I use Suse 6.1, kernel 2.2.7. _____________________________________________________________ Do You Yahoo!?
