PPS on Amiga serial port?

Hi,

Does anyone know if PPS is supported on Amiga serial ports?

Thanks,
John

Hardware-wise it should be supported. AFAIK the DCD line is used for it?
I'm not sure if and where PPS support is implemented in NetBSD, though.

I tried it again, some days ago, with the official 4.0, and the X-server is
coming up in 16-bit, even starting parts of Gnome...

Strange. Maybe we should close this PR for now.

Ere you get fancy ideas:  We don't have any hardware DCD interupt,
we poll in the vertical blank interupt for that (see below). So
the clock resolution of the PPS signal is the 16.666ms or 20ms vertical
blank interupt.

From sys/arch/amiga/dev/ser.c:
/*
 * This interrupt is periodically invoked in the vertical blank
 * interrupt.  It's used to keep track of the modem control lines
 * and (new with the fast_int code) to move accumulated data
 * up into the tty layer.
 */
void
sermint(int unit)
