probemodem - check modem and report the result of certain commands SYNOPSIS
/usr/sbin/probemodem [-f] [-c AT_COMMAND] [-s SPEED] [ttyname] DESCRIPTION
The probemodem script checks a modem attached to a serial line and reports the results of certain commands. The ttyname argument is the name of the tty port that the modem is attached to. This manual page was written for the Debian GNU/Linux distribution (but may be used by others), because the original program does not have a manual page. OPTIONS
-f Do not use the command fuser in order to check if other processes are using the tty ttyname and kill them -c AT_COMMAND Specify a string to be sent to the modem instead of "AT+FCLASS=?" -s speed Set the speed to use for the ttyname port SEE ALSO

slattach -- attach serial lines as network interfaces SYNOPSIS
slattach [-Hhlmn] [-s baudrate] [-t ldisc] ttyname DESCRIPTION
slattach is used to assign a tty line to a network interface which uses asynchronous serial lines. Currently the slattach command is used to attach sl(4) or strip(4) interfaces. These interfaces have to be created using the ifconfig(8) create subcommand before the slattach command. The network source and destination addresses and other interface parameters are configured via ifconfig(8). The following operands are supported by slattach: -H Turn on DTR/CTS flow control. By default, no flow control is done. -h Turn on RTS/CTS flow control. By default, no flow control is done. -l Turn on the CLOCAL flag, making it possible to run SLIP on a cable without modem control signals (e.g. DTR, DSR, DCD). -m Maintain modem control signals after closing the line. Specifically, this disables HUPCL. -n Don't detach from invoking tty. -s baudrate Specifies the speed of the connection. If not specified, the default of 9600 is used. -t ldisc Specifies the line discipline to use for the tty. Supported line disciplines are ``slip'' (creates a sl(4) instance) and ``strip'' (creates a strip(4) instance). If this option is not specified, the default is ``slip''. ttyname Specifies the name of the tty device. ttyname should be a string of the form 'ttyXX', or '/dev/ttyXX'. Only the super-user may attach a network interface. To detach the interface, use ``ifconfig interface-name down'' after killing off the slattach process. Interface-name is the name that is shown by netstat(1). EXAMPLES
slattach ttyh8 slattach -s 4800 /dev/tty01 DIAGNOSTICS
Messages indicating that the specified interface is not configured or created, the requested address is unknown, or that the user is not privileged but tried to alter an interface's configuration. SEE ALSO
netstat(1), daemon(3), netintro(4), sl(4), strip(4), ifconfig(8), rc(8), sliplogin(8), slstats(8) HISTORY
The slattach command appeared in 4.3BSD. BUGS
There is no way to specify the interface name (sl%d etc.) to be attached by the slattach command. There is no way to see which interface is assigned to the specified tty by the slattach command, either. It would be better if the network interfaces were created by the slattach command rather than by using the ifconfig(8) create subcommand before the slattach command. BSD
