Greetings.

..followup to my original posting on how to get a Sun to ticktock with 
electrical pulses. The most promising response I received was to try 
ppsclock in the NTP distribution.

Anyone have any experience with ppsclock? The following test code which 
should make the front panel LED blink compiles but cores and I have no 
documentation on using AUXIO_REG. I'm using a Sparc 5 and Sparc 20 under 
Solaris 2.5.

#include <sys/param.h>
#include "/usr/platform/sun4m/include/sys/auxio.h"
#define	LED_ON		*(u_char *)AUXIO_REG = AUX_MBO|AUX_EJECT|AUX_LED
#define	LED_OFF		*(u_char *)AUXIO_REG = AUX_MBO|AUX_EJECT
main() {
while (1) {
  LED_OFF;
  sleep(1);
  LED_ON;
  sleep(1);
}
}


Thanks.
