NAME <\/a> <\/h2>\n

ldattach \u2212 attach a line discipline to a serial line<\/p>\n

SYNOPSIS <\/a> <\/h2>\n

ldattach<\/b> [\u22121278denoVh<\/b>] [\u2212i<\/b> iflag<\/i>] [\u2212s<\/b> speed<\/i>] ldisc device<\/i><\/p>\n

DESCRIPTION <\/a> <\/h2>\n

The ldattach<\/b> daemon opens the specified device<\/i> file (which should refer to a serial device) and attaches the line discipline ldisc<\/i> 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.<\/p>\n

The line discipline ldisc<\/i> may be specified either by name or by number.<\/p>\n

In order to detach the line discipline, kill<\/b>(1) the ldattach<\/b> process.<\/p>\n

With no arguments, ldattach<\/b> prints usage information.<\/p>\n

LINE DISCIPLINES <\/a> <\/h2>\n

Depending on the kernel release, the following line disciplines are supported:<\/p>\n\n\n
<\/td>\n\n

TTY<\/b>(0<\/b>)<\/p>\n<\/td>\n

Bluetooth HCI UART driver.<\/p>\n

GIGASET_M101<\/b>(16<\/b>)<\/p>\n

Driver for Siemens Gigaset M101 serial DECT adapter.<\/p>\n

PPS<\/b>(18<\/b>)<\/p>\n

Driver for serial line Pulse Per Second (PPS) source.<\/p>\n

GSM0710<\/b>(21<\/b>)<\/p>\n

OPTIONS <\/a> <\/h2>\n

\u22121<\/b>, \u2212\u2212onestopbit<\/b><\/p>\n

Set the number of stop bits of the serial line to one.<\/p>\n

\u22122<\/b>, \u2212\u2212twostopbits<\/b><\/p>\n

Set the number of stop bits of the serial line to two.<\/p>\n

\u22127<\/b>, \u2212\u2212sevenbits<\/b><\/p>\n

Set the character size of the serial line to 7 bits.<\/p>\n

\u22128<\/b>, \u2212\u2212eightbits<\/b><\/p>\n

Set the character size of the serial line to 8 bits.<\/p>\n

\u2212d<\/b>, \u2212\u2212debug<\/b><\/p>\n

Keep ldattach<\/b> in the foreground so that it can be interrupted or debugged, and to print verbose messages about its progress to standard error output.<\/p>\n

\u2212e<\/b>, \u2212\u2212evenparity<\/b><\/p>\n

Set the parity of the serial line to even.<\/p>\n

\u2212i<\/b>, \u2212\u2212iflag<\/b> [\u2212<\/b>]value<\/i>…<\/p>\n

Set the specified bits in the c_iflag word of the serial line. The given value<\/i> may be a number or a symbolic name. If value<\/i> 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.<\/p>\n

\u2212n<\/b>, \u2212\u2212noparity<\/b><\/p>\n

Set the parity of the serial line to none.<\/p>\n

\u2212o<\/b>, \u2212\u2212oddparity<\/b><\/p>\n

Set the parity of the serial line to odd.<\/p>\n

\u2212s<\/b>, \u2212\u2212speed<\/b> value<\/i><\/p>\n

Set the speed (the baud rate) of the serial line to the specified value<\/i>.<\/p>\n

\u2212c<\/b>, \u2212\u2212intro\u2212command<\/b> string<\/i><\/p>\n

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 \u00b4AT+CMUX=0r\u00b4 is commonly suitable to switch the modem into the CMUX mode.<\/p>\n

\u2212p<\/b>, \u2212\u2212pause<\/b> value<\/i><\/p>\n

Sleep for value<\/i> seconds before the invocation of ldattach. Default is one second.<\/p>\n

\u2212V<\/b>, \u2212\u2212version<\/b><\/p>\n

Display version information and exit.<\/p>\n

\u2212h<\/b>, \u2212\u2212help<\/b><\/p>\n

Display help text and exit.<\/p>\n
