DESCRIPTION

13       The  <termios.h>  header  contains the definitions used by the terminal
14       I/O interfaces. See termios(3C) and termio(7I) for an overview  of  the
15       terminal interface.
16
17   The termios Structure
18       The following data types are defined through typedef:
19
20       cc_t        used for terminal special characters
21
22
23       speed_t     used for terminal baud rates
24
25
26       tcflag_t    used for terminal modes
27
28
29
30       The above types are all unsigned integer types.
31
32
33       The  implementation  supports  one  or more programming environments in
34       which the widths of cc_t, speed_t, and tcflag_t are no greater than the
35       width  of type long. The names of these programming environments can be
36       obtained using the confstr(3C) function or the getconf(1) utility.
37
38
39       The termios structure is defined and includes the following members:
40
41         tcflag_t c_iflag        /* input modes */
42         tcflag_t c_oflag        /* output modes */
43         tcflag_t c_cflag        /* control modes */
44         tcflag_t c_lflag        /* local modes */
45         cc_t     c_cc[NCCS]     /* control characters */
46
47
48
49       A definition is provided for:
50
51       NCCS    size of the array c_cc for control characters
52
53
54
55       The following subscript names for the array c_cc are defined:

79       respectively.

264   Control Modes
265       The  c_cflag  field describes the hardware control of the terminal; not

267       hardware:
268
269       CSIZE     Character size:
270
271                 CS5    5 bits
