NAME
ldattach - attach a line discipline to a serial line SYNOPSIS
ldattach [-dhV78neo12] [-s speed] [-i iflag] 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. -i value | --iflag [-]value{,...} Sets the specified bits in the c_iflag word of the serial line. Value may be a number or a symbolic name. If value is prefixed by a minus sign, clear the specified bits instead. Several comma separated values may be given in order to set and clear multiple bits.
