[LinuxPPS] Setting the serial port to match the refclock

[clemens at dwf.com]

> My refclock defaults to 9800,7,even,1.  It seems that the serial port (/dev/ttyS0)defaults to 115000 (and I'm not sure what else).  I do not see how NTP configures the serial port.  Can someone help me out with serial port configuration?

Im not sure which driver you are using, but the oncore driver opens the device 
and sets the
speed with a line like

        if (!(fd1 = refclock_open(device1, SPEED, LDISC_RAW))) {    

where SPEED was previously defined with the line

        #define SPEED           B9600           /* Oncore Binary speed (9600 
bps) */

I would assume that other drivers so something similar, setting the line speed 
on their open.

In this case (the ONCORE) LDISC_RAW does what you would expect, but there are 
other LDISC_
options, and you MIGHT find them defined in a *.h file, or you might have to 
grep the code
to find where they are used, and then grub thru the code to see what is 
actually set.
