+.SH NAME
+TIOCGSOFTCAR,
+TIOCSSOFTCAR
+\-
+marking a line as local
+.SH LIBRARY
+Standard C library

+.SH SYNOPSIS

+.BR "#include <asm/termbits.h>" "  /* Definition of " TIOC*SOFTCAR " constants */"
+.B #include <sys/ioctl.h>

+.SH DESCRIPTION
+.TP
+.B TIOCGSOFTCAR
+("Get software carrier flag")
+Get the status of the CLOCAL flag in the c_cflag field of the
+.I termios
+structure.
+.TP
+.B TIOCSSOFTCAR
+("Set software carrier flag")
+Set the CLOCAL flag in the
+.I termios
+structure when
+.RI * argp
+is nonzero, and clear it otherwise.
+.P
+If the
+.B CLOCAL
+flag for a line is off, the hardware carrier detect (DCD)
+signal is significant, and an
+.BR open (2)
+of the corresponding terminal will block until DCD is asserted,
+unless the
+.B O_NONBLOCK
+flag is given.
+If
+.B CLOCAL
+is set, the line behaves as if DCD is always asserted.
+The software carrier flag is usually turned on for local devices,
+and is off for lines with modems.
+.SH RETURN VALUE
+On success,
+0 is returned.
+On error,
+\-1 is returned, and
+.I errno
+is set to indicate the error.
