I've been having tons of trouble getting the PPSAPI to work under Linux
2.4.34. I've applied the 2.4.32 patches, recompiled the kernel and ntpd,
and have reached the stage where ntpdc -c kern shows nano as one of the
I have however just noticed that the serial driver was probably not
being compiled with the right options, because if it is compiled as a
module CONFIG_NTP_PPS_SERIAL if #undef'd, whereas
CONFIG_NTP_PPS_SERIAL_MODULE is #defined instead. I _think_ that this
causes serial.c to skip all of the PPS code (and indeed: the serial
driver startup line in /var/log/messages does not show the PPSAPI flag).
Morale: if you need PPS support don't compile the serial driver as a module.
