The application I try to port has to read in ascii lines at 1200baud,
7 databits, 1 stopbit even parity. The lines all end with 'Carriage Return'.
What is de sysV rel 2 code for the underneath routine (used in BSD4.3)?
------------------------------------------------------
/* set speed etc. of communication line */
open_line()
{
struct sgttyb ttybuf;
close(0);
if(fdc = open("/dev/ttyd0", 0) < 0) return(0);
if(ioctl(0, TIOCEXCL, (char *)0) < 0 ||
ioctl(0, TIOCGETP, (char *)&ttybuf) < 0) return(0);
ttybuf.sg_ispeed = B1200;
ttybuf.sg_flags = 0;
ttybuf.sg_flags |= XTABS|ECHO|FF1|CRMOD;
if(ioctl(0, TIOCSETP, (char *)&ttybuf) < 0) return(0);
return(1);
}

AS you will expect, I am not an experienced C programmer and certainly not
when serial lines handling is the topic.
