Hello,
I am working on porting some Linux code to FreeBSD. Specifically, I received
a sample program from CrystalFontz to drive their CFA633 intelligent LCD
module.
The problem is in the serial I/O file. There are several references to
defines that aren't in the FreeBSD termios.h file.
In particular, this is what I get when I try to compile their code:
serial.c: In function `Serial_Init':
serial.c:91: `IUCLC' undeclared (first use in this function)
serial.c:91: (Each undeclared identifier is reported only once
serial.c:91: for each function it appears in.)
serial.c:95: `OLCUC' undeclared (first use in this function)
serial.c:96: `OFILL' undeclared (first use in this function)
serial.c:96: `OFDEL' undeclared (first use in this function)
serial.c:96: `NLDLY' undeclared (first use in this function)
serial.c:96: `CRDLY' undeclared (first use in this function)
serial.c:96: `TABDLY' undeclared (first use in this function)
serial.c:96: `BSDLY' undeclared (first use in this function)
serial.c:96: `VTDLY' undeclared (first use in this function)
serial.c:96: `FFDLY' undeclared (first use in this function)
serial.c:97: `NL0' undeclared (first use in this function)
serial.c:97: `CR0' undeclared (first use in this function)
serial.c:97: `TAB0' undeclared (first use in this function)
serial.c:97: `BS0' undeclared (first use in this function)
serial.c:97: `VT0' undeclared (first use in this function)
serial.c:97: `FF0' undeclared (first use in this function)
The code in question is:
//input modes
term.c_iflag &=
~(IGNBRK|BRKINT|PARMRK|INPCK|ISTRIP|INLCR|IGNCR|ICRNL
|IUCLC|IXON|IXANY|IXOFF|IMAXBEL);
term.c_iflag |= IGNPAR;
//output modes
term.c_oflag &= ~(OPOST|OLCUC|ONLCR|OCRNL|ONOCR|ONLRET|OFILL
|OFDEL|NLDLY|CRDLY|TABDLY|BSDLY|VTDLY|FFDLY);
term.c_oflag |= NL0|CR0|TAB0|BS0|VT0|FF0;
//control modes
term.c_cflag &= ~(CSIZE|PARENB|CRTSCTS|PARODD|HUPCL);
term.c_cflag |= CREAD|CS8|CSTOPB|CLOCAL;
//local modes
term.c_lflag &= ~(ISIG|ICANON|IEXTEN|ECHO|FLUSHO|PENDIN);
term.c_lflag |= NOFLSH;
//set baud rate
cfsetospeed(&term, brate);
cfsetispeed(&term, brate);
//set new device settings
if (tcsetattr(handle, TCSANOW, &term) != 0)
{
printf("tcsetattr failed\n");
return(4);
}
Some of the defines are in the FreeBSD termios.h, but I'm not sure if they
are trustworthy. Can anyone tell me what these defines should be?
Also, aren't these part of the POSIX spec? If so, what's the deal?
Thanks,
Seth Henry
