Has anyone successfully implemented NTP on the IBM Risc System 6000
running AIX3.1? If so, can you send installation instructions? Thanks.

I don't know if this applies to IBM RS-6000 machines or not, but on Silicon Graphics systems, SIGIO works only on sockets, and SIGPOLL works on streams devices (/dev/tty*). Once I discovered that, our TrueTime clock seems to be working fine. Since input_handler() doesn't care which signal invokes it, the changes were rather minor. -- Scott Henry <scotth@sgi.com> / Traveller on Dragon Wings Information Services, / Help!
