DESCRIPTION

     Stty shows or changes the parameters of  the  terminal  con-
     nected  to standard input.  Stty takes a myriad of arguments
     most of which are mapped directly to the flags  and  special
     characters  described  in  tty(4), so we won't describe them
     here.

     Stty has three forms of operation.  First, without any argu-
     ments  stty shows all terminal attributes that are different
     from the default state.  Option -a makes stty print all ter-
     minal attributes, and -g lets stty print the attributes in a
     special encoded form, a simple row of colon separated  hexa-
     decimal numbers.

     In the second form of operation stty takes an  encoded  form
     as  produced  by the -g option and sets the terminals attri-
     butes to its decoded value.

     In the third form stty interprets  a  series  of  flags  and
     parameters  settings  and  modifies  the terminal attributes
     accordingly.  Flags can be given as icanon  or  -icanon  for
     instance,  either setting or clearing the ICANON flag.  Spe-
     cial character values can by set like intr=^C  for  example,
     which  sets  the  interrupt  character  to  CTRL-C.  You can
     either use a real CTRL-C, or the two characters `^' and `C'.
     In  any case it is probably necessary to use quotes to guard
     it from the shell:  intr='^C'.

     A number alone is interpreted as a  baud  rate  setting  for
     both  the  input  and  output rate.  The input or the output
     rate can be set separately with use of the ispeed and ospeed
     prefixes  to the number.  The character size can be set with
     cs5, cs6, cs7 or cs8.

     The MIN and TIME value, the number of rows and columns,  and
     the  xpixels and ypixels of the window can also be set using
     one of the keywords min, time, rows, cols, xpixels or  ypix-
     els,  followed  by a decimal number that is the value of the
     setting.

     Stty  accepts  several  keywords  that  are  not  named   by
     corresponding  flags  or  parameters  in  tty(4).   They set
     several attributes at once:

     cooked
          Same as icrnl ixon opost onlcr isig icanon iexten echo,
          setting  all  the  attributes  that are needed for line
          oriented mode.

     raw  Same as -icrnl -ixon -opost -onlcr -isig -icanon  -iex-
          ten  -echo,  setting  all the attributes for a raw data
          channel.

     evenp parity
          These synonyms are equal to cs7 parenb -parodd, setting
          the line to 7 bits even parity.

     oddp Same as cs7 parenb parodd, setting the line to  7  bits
          odd parity.

     -parity -evenp -oddp
          All synonyms for cs8 -parenb, setting  the  line  to  8
          bits, no parity.

     nl   Same as icrnl, setting carriage  return  to  line  feed
          input translation.

     -nl  Same as -icrnl -inlcr -igncr,  disabling  any  carriage
          return or line feed handling.

     ek   Set the ERASE and KILL special characters back  to  the
          default.

     sane Set all attributes to the default  except  things  like
          the  line  speed and parity, because their "sane" value
          is probably what it is right now.  The  default  values
          are  compiled  into  stty  from the <termios.h> include
          file.  Use stty sane; stty -a to know what they are.


FILES

     /etc/ttytab    The init field of this file  may  contain  an
                    stty  command  to set the attributes to match
                    an attached RS232 terminal or modem.


SEE ALSO

     tty(4), ttytab(5).


NOTES

     The cooked, raw, rows, cols, xpixels  and  ypixels  keywords
     are  MINIX 3 additions beyond the keywords defined by POSIX.
     Rows and cols are common UNIX  extensions,  however.   There
     are  more  MINIX  3  specific  flags  that match the MINIX 3
     specific attributes described in tty(4).
