Kill a running daemon.

Check if a daemon is running. Sets the return value to 0 if a daemon is already running or to 255 if not.

Specifies how many ISDN channels to allocate. It should be greater or equal to one. Keep in mind that a standard ISDN card provides access to two distinct b channels only. Unless you have special hardware or more than one ISDN card in a single machine it makes no sense to set this paramater to any value greater than 2. This value specifies how many concurrent connections may be handled. (default: 2)

Specify another msntab file than the default. (default: @pkgsysconfdir@/msntab)

Specifies which local phone numbers ivamd shall listen on. The incoming phone number is matched with shell globbing as described in with the extension that you may list more than one phone number seperated by commas or semicolons. (This is described in for the command AT&L. Before passing the MSNs to the ISDN modem emulation ivamd replaces all occurences of "," to ";". This has certain advantages when passing the options from the bourne shell.) In addition to that you may specify more than one globbing string seperated by colons for different ISDN channels. If you specify fewer globbing strings than allocated channels the last globbing string will be reused for all excessive channels. It is safe to set this option to "*" as you may limit access to your telephony applications with the msntab file in a more powerful way. This option is only useful as "second line of defense" or to assign specific phone numbers to specific channels. (default: *)

Specifies the TTY devices to use. You may specify more than one device separated by colons. All devices specified in this option will be opened, regardless of the argument of the -C option. If you specify fewer devices than the requested number of channels, all missing channels will be allocated automatically from the /dev/ttyI pool. The devices specified with this option are opened prior to the automatic usage of the ttyI devices. (default: empty, thus all devices will be allocated from the /dev/ttyI pool.)

If this option is given ivamd will not drop root priviliges and change to ivam:ivam. To stay root is always a bad idea, so don't use this for anything but debugging. (default: off)

Send a running daemon a HUP signal, thus causing a msntab reload.

Send a running daemon an USR1 signal, thus causing it to dump its msntab file to syslog.
