I still have the same problem with CentOS 5.4, 5.6 and 5.7 x86_64.
I tried using the lastest available driver : dgnc-1.3.28.
I also updated the /etc/init.d/dgnc by replacing :
/usr/sbin/dgnc_mknod $n $rest
by
/sbin/dgnc_mknod $n $rest
and copy all the /usr/sbin/dgnc_* to /sbin but with no success.
Finally I added in /etc/rc.local a restart of the dgnc service :
service dgnc stop
service dgnc start
And now the naming are correct.
But my problem is that I have some services which are using the serial ports and which start before the good naming of serials ports. So they failed.
It seems that I’m not the only one to have this problem.
Do you find any solution for that ?
Did you success to start the dgnc as a service under Red-Hat 5.X with a correct serial port naming ?
