I assume you mean pps_core, which I do have. Unfortunately nothing seems to happen. If I try ldattach 18 /dev/ttyS0 ( and yes there is a ttyS0 ) I get an error message "ldattach: cannot set line discipline: Invalid argument" I have no idea which serial port modules I should have loaded. There is no 8250 module, mentioned in some places. The serial port works so some module, or some in kernel drivers are in place. > > > uwe _______________________________________________ questions mailing list [email protected] http://lists.ntp.org/listinfo/questions
