 | 	does not cause a SIGIO to be delivered in this setup.
 | 	ntpd pretends to run because of network SIGIOs, but ntpd is
 |         unable to actually use a tty refclock as input on a TTY as
 | 	input is batched in intervals of network caused SIGIOs.
 | 
 | 	So, currently ntpd refclock support is broken.
 
 Does the code set FIOASYNC?
