NAME
stty - terminal interface for Version 6/PWB compatibility
REMARKS
These facilities are included to aid in conversion of old programs,
and should not be used in new code. Use the interface described in
termio(7). Note that these conversions do not work for programs
ported from UNIX Time-Sharing System, Seventh Edition (Version 7),
because some V7 flags are defined differently.
DESCRIPTION
These routines attempt to map the UNIX Time-Sharing System, Sixth
Edition (Version 6), and PWB stty and gtty calls into the current
ioctls that perform the same functions. The mapping cannot be
perfect. The way the features are translated is described below. The
reader should be familiar with termio(7) before studying this entry.
The following data structure is defined in the include file <sgtty.h>:
struct sgttyb {
char sg_ispeed; /* input speed */
char sg_ospeed; /* output speed */
char sg_erase; /* erase character */
char sg_kill; /* kill character */
int sg_flags; /* mode flags */
}
The flags, as defined in sgtty.h, are:
l l. #define HUPCL 01 #define XTABS 02 #define
LCASE 04 #define ECHO 010 #define
CRMOD 020 #define RAW 040 #define ODDP 0100
#define EVENP 0200 #define ANYP 0300 #define
NLDELAY 001400 #define TBDELAY 002000 #define
CRDELAY 030000 #define VTDELAY 040000 #define
BSDELAY 0100000
#define CR0 0 #define CR1 010000 #define CR2 020000 #define CR3 030000
#define NL0 0 #define NL1 000400 #define NL2 001000 #define NL3 001400
#define TAB0 0 #define TAB1 002000 #define
NOAL 004000 #define FF0 0 #define FF1 040000 #define BS0 0
#define BS1 0100000
When the stty(2) command (ioctl TIOCSETP) is executed, the flags in
the old sgttyb structure are mapped into their new equivalents in the
termio structure. Then the TCSETA command is executed.
The following table shows the mapping between the old sgttyb flags and
the current termio flags. Note that flags contained in the termio
structure that are not mentioned below are cleared.

HUPCL (if set) sets the termio HUPCL flag;

XTABS (if clear) clears the termio TAB3 flag;
TBDELAY (if set) sets the termio TAB1 flag;
TBDELAY (if clear) clears the termio TAB1 flag;
LCASE (if set) sets the termio IUCLC, OLCUC, and XCASE flags;
LCASE (if clear) clears the termio IUCLC, OLCUC, and XCASE
flags;
ECHO (if set) sets the termio ECHO flag;
ECHO (if clear) clears the termio ECHO flag;
NOAL (if set) sets the termio ECHOK flag;
NOAL (if clear) clears the termio ECHOK flag;
CRMOD (if set) sets the termio ICRNL and ONLCR flags; also,
if CR1 is set, the termio CR1 flag is set, and if CR2
is set, the termio ONOCR and CR2 flags are set;
CRMOD (if clear) sets the termio ONLRET flag; also, if NL1 is
set, the termio CR1 flag is set, and if NL2 is set, the
termio CR2 flag is set;
RAW (if set) sets the termio CS8 flag, and clears the
termio ICRNL and IUCLC flags; also, default values of 6
characters and 0.1 seconds are assigned to MIN and
TIME, respectively;
RAW (if clear) sets the termio BRKINT, IGNPAR, ISTRIP,
IXON, IXANY, OPOST, CS7, PARENB, ICANON, and ISIG
flags; also, the default values control-D and null are
assigned to the control characters EOF and EOL,
respectively;
ODDP (if set) if EVENP is also set, clears the termio INPCK
flag; otherwise, sets the termio PARODD flag;
VTDELAY (if set) sets the termio FFDLY flag;
VTDELAY (if clear) clears the termio FFDLY flag;
BSDELAY (if set) sets the termio BSDLY flag;
BSDELAY (if clear) clears the termio BSDLY flag.
In addition, the termio CREAD bit is set, and, if the baud rate is
110, the CSTOPB bit is set.
When using TIOCSETP, the ispeed entry in the sgttyb structure is
mapped into the appropriate speed in the termio CBAUD field. The
erase and kill sgttyb entries are mapped into the termio erase and
kill characters.
When the gtty(2) (ioctl TIOCGETP) command is executed, the termio(7)
TCGETA command is first executed. The resulting termio structure is
then mapped into the sgttyb structure, which is then returned to the
user.
The following table shows how the termio flags are mapped into the old
sgttyb structure. Note that all flags contained in the sgttyb
structure that are not mentioned below are cleared.

ICANON (if set) sets the sgttyb RAW flag;
ICANON (if clear) clears the sgttyb RAW flag;
XCASE (if set) sets the sgttyb LCASE flag;
XCASE (if clear) clears the sgttyb LCASE flag;
ECHO (if set) sets the sgttyb ECHO flag;

flags;

set, the sgttyb CR1 flag is set, and if CR2 is set, the
sgttyb CR2 flag is set;
ONLCR (if clear) if CR1 is set, the sgttyb NL1 flag is set,
and if CR2 is set, the sgttyb NL2 flag is set;
TAB3 (if set) sets the sgttyb XTABS flag;
TAB3 (if clear) clears the sgttyb XTABS flag;
TAB1 (if set) sets the sgttyb TBDELAY flag;
TAB1 (if clear) clears the sgttyb TBDELAY flag;
FFDLY (if set) sets the sgttyb VTDELAY flag;
FFDLY (if clear) clears the sgttyb VTDELAY flag;
BSDLY (if set) sets the sgttyb BSDELAY flag;
BSDLY (if clear) clears the sgttyb BSDELAY flag.
When using TIOCGETP, the termio CBAUD field is mapped into the ispeed
and ospeed entries of the sgttyb structure. Also, the termio erase
and kill characters are mapped into the erase and kill sgttyb entries.
Note that, since there is not a one-to-one mapping between the sgttyb
and termio structures, unexpected results may occur when using the
older TIOCSETP and TIOCGETP calls. Thus, the TIOCSETP and TIOCGETP
calls should be replaced in all future code by the current
equivalents, TCSETA and TCGETA, respectively.
