+== 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 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.
+
+*GSM0710*(*21*)::
+Driver for GSM 07.10 multiplexing protocol modem (CMUX).
+
+== 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 specified _value_.
+
+*-c*, *--intro-command* _string_::
+Define an intro command that is sent through the serial line before the invocation of *ldattach*. E.g. in conjunction with line discipline GSM0710, the command 'AT+CMUX=0\r' is commonly suitable to switch the modem into the CMUX mode.
+
+*-p*, *--pause* _value_::
+Sleep for _value_ seconds before the invocation of *ldattach*. Default is one second.
