>Description:
I have a custom application (MDB interface software) that runs under FreeBSD. The MDB spec calls for 9 bit words on the serial port and some other bizarre settings. What worked on 2.2.8, 3.0-RELEASE does not work on the 3.1-RELEASE system
>How-To-Repeat:
It may be hard if you do not have a device that supports 9-bit parity enabled serial communications but this works under 3.0 and not 3.1:
{ // Mode bit SET
tty.c_cflag = CS8;
tty.c_cflag |= CREAD;
tty.c_cflag |= CLOCAL;
tty.c_cflag &= ~HUPCL;
}
if (tcsetattr(fd, TCSANOW, &tty) == -1)
{
perror("tcsetattr");
exit(1);
}
>Fix:
I do not have the time to find out what happened to the sio code, however I am definately more than willing to help.
