There is value in ensuring that manual page sections use consistently
named sections, as far as possible, and also that sections have a
consistent order within manual pages. This is one of a series of patches
to place manual page sections in a consistent order.
In this patch, we ensure that the AUTHORS, COPYRIGHT, SEE ALSO, and
AVAILABILITY sections are always placed at the end of the page.
Testing that no gross editing mistake (causing accidental loss or addition
of text) was performed as follows:
$ cat $(grep '\.SH' -l $(find . -name '*.[1-9]') |sort) | sort > a
[Apply patch]
$ cat $(grep '\.SH' -l $(find . -name '*.[1-9]') |sort) | sort > b
$ diff a b
$ echo $?

.SH NAME
|
|
ldattach \- attach a line discipline to a serial line
|
|
.SH SYNOPSIS
|
|
.B ldattach
|
|
.RB [ \-1278denoVh ]
|
|
.RB [ \-i
|
|
.IR iflag ]
|
|
.RB [ \-s

|
|
.I ldisc device
|
|
.SH DESCRIPTION
|
|
The
|
|
.B ldattach
|
|
daemon opens the specified
|
|
.I device
|
|
file
|
|
(which should refer to a serial device)
|
|
and attaches the line discipline
|
|
.I 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.
|
|
.sp
|
|
The line discipline
|
|
.I ldisc
|
|
may be specified either by name
|
|
or by number.
|
|
.sp
|
|
In order to detach the line discipline,
|
|
.BR kill (1)
|
|
the
|
|
.B ldattach
|
|
process.
|
|
.sp
|
|
With no arguments,
|
|
.B ldattach
|
|
prints usage information.
|
|

.SH OPTIONS
|
|
.TP
|
|
.BR \-1 , " \-\-onestopbit"
|
|
Set the number of stop bits of the serial line to one.
|
|
.TP
|
|
.BR \-2 , " \-\-twostopbits"
|
|
Set the number of stop bits of the serial line to two.
|
|
.TP
|
|
.BR \-7 , " \-\-sevenbits"
|
|
Set the character size of the serial line to 7 bits.
|
|
.TP
|
|
.BR \-8 , " \-\-eightbits"
|
|
Set the character size of the serial line to 8 bits.
|
|
.TP
|
|
.BR \-d , " \-\-debug"
|
|
Keep
|
|
.B ldattach
|
|
in the foreground so that it can be interrupted or debugged,
|
|
and to print verbose messages about its progress to standard error output.
|
|
.TP
|
|
.BR \-e , " \-\-evenparity"
|
|
Set the parity of the serial line to even.
|
|
.TP
|
|
.BR \-i , " \-\-iflag " [ \- ] \fIvalue\fR...
|
|
Set the specified bits in the c_iflag word of the serial line.
|
|
The given \fIvalue\fP may be a number or a symbolic name.
|
|
If \fIvalue\fP 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.
|
|
.TP
|
|
.BR \-n , " \-\-noparity"
|
|
Set the parity of the serial line to none.
|
|
.TP
|
|
.BR \-o , " \-\-oddparity"
|
|
Set the parity of the serial line to odd.
|
|
.TP
|
|
.BR \-s , " \-\-speed " \fIvalue
|
|
Set the speed (the baud rate) of the serial line to the specified \fIvalue\fR.
|
|
.TP
|
|
.BR \-c , " \-\-intro\-command " \fIstring
|
|
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.
|
|
.TP
|
|
.BR \-p , " \-\-pause " \fIvalue
|
|
Sleep for \fIvalue\fR seconds before the invocation of ldattach. Default is one second.
|
|
.TP
|
|
.BR \-V , " \-\-version"
