ldattach

LDATTACH(8)						     Linux Programmer's Manual						       LDATTACH(8)

NAME

       ldattach - attach a line discipline to a serial line

SYNOPSIS

       ldattach [-dhV78neo12] [-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 capabilities
	      (cooked mode).

       SLIP(1)
	      Serial Line IP (SLIP) protocol processor for transmitting TCP/IP packets over serial lines.

       MOUSE(2)
	      Device driver for RS232 connected pointing devices (serial mice).

       PPP(3) Point to Point Protocol (PPP) processor for transmitting network packets over serial lines.

       STRIP(4)

       AX25(5)

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

       6PACK(7)

       R3964(9)
	      Driver for Simatic R3964 module.

       IRDA(11)
	      Linux IrDa (infrared data transmission) driver - see http://irda.sourceforge.net/

       HDLC(13)
	      Synchronous HDLC driver.

       SYNC_PPP(14)
	      Synchronous PPP driver.

       HCI(15)
	      Bluetooth HCI UART driver.

       GIGASET_M101(16)
	      Driver for Siemens Gigaset M101 serial DECT adapter.

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

OPTIONS

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

       -h | --help
	      Prints a usage message and exits.

       -V | --version
	      Prints the program version.

       -s value | --speed value
	      Set the speed of the serial line to the specified value.

       -7 | --sevenbits
	      Sets the character size of the serial line to 7 bits.

       -8 | --eightbits
	      Sets the character size of the serial line to 8 bits.

       -n | --noparity
	      Sets the parity of the serial line to none.

       -e | --evenparity
	      Sets the parity of the serial line to even.

       -o | --oddparity
	      Sets the parity of the serial line to odd.

       -1 | --onestopbit
	      Sets the number of stop bits of the serial line to one.

       -2 | --twostopbits
	      Sets the number of stop bits of the serial line to two.
