== 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*)::

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*)::
|
|

|
|
|
|
*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.
|
|
|
|
*-V*, *--version*::
|
|
Display version information and exit.
|
|
|
|
*-h*, *--help*::
|
|
Display help text and exit.
