ooops. That's what I get for using a V1.0 newsreader (name withheld).

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.
