NAME
       ldattach - attach a line discipline to a serial line

SYNOPSIS
       ldattach [-1278denoVh] [-i iflag] [-s speed] ldisc device

DESCRIPTION
       The ldattach daemon opens the specified device file (which should refer
       to a serial device) and attaches the line discipline ldisc  to  it  for
       processing  of  the  sent  and/or received data.  It then goes into the
       background keeping the device open so that the  line  discipline  stays
       loaded.

       The line discipline ldisc may be specified either by name or by number.

       In order to detach the line discipline, kill(1) the ldattach process.

       With no arguments, ldattach prints usage information.

LINE DISCIPLINES
       Depending  on  the  kernel  release, the following line disciplines are
       supported:

       TTY(0) The default line  discipline,  providing  transparent  operation
              (raw  mode)  as well as the habitual terminal line editing capa-
              bilities (cooked mode).

       SLIP(1)

              packets over serial lines.

       STRIP(4)

       AX25(5)

       X25(6) Line  driver  for  transmitting  X.25  packets over asynchronous
              serial lines.

              http://irda.sourceforge.net/

       HDLC(13)
              Synchronous HDLC driver.

       SYNC_PPP(14)
              Synchronous PPP driver.

       HCI(15)
              Bluetooth HCI UART driver.

              Driver for Siemens Gigaset M101 serial DECT adapter.

       PPS(18)
              Driver for serial line Pulse Per Second (PPS) source.

OPTIONS
       -1, --onestopbit
              Set the number of stop bits of the serial line to one.

       -2, --twostopbits
              Set the number of stop bits of the serial line to two.

       -7, --sevenbits
              Set the character size of the serial line to 7 bits.

       -8, --eightbits
              Set the character size of the serial line to 8 bits.

       -d, --debug
              Keep ldattach in the foreground so that it can be interrupted or
              debugged, and to print verbose messages about  its  progress  to
              standard error output.

       -e, --evenparity
              Set the parity of the serial line to even.

       -i, --iflag [-]value...
              Set  the  specified bits in the c_iflag word of the serial line.
              The given value may be a number or a symbolic name.  If value is
              prefixed  by  a  minus  sign,  the  specified  bits  are cleared
              instead.  Several comma-separated values may be given  in  order
              to set and clear multiple bits.

       -n, --noparity
              Set the parity of the serial line to none.

       -o, --oddparity
              Set the parity of the serial line to odd.

       -s, --speed value
              Set  the  speed (the baud rate) of the serial line to the speci-
              fied value.

       -V, --version
              Display version information and exit.

       -h, --help
              Display help text and exit.
