102APPENDIX : COMMAND LINE INTERFACE

An "x" placed at the beginning of any IP Telephony Manager command omits command parameters and the target slot and channel designation-only the target IP address or hostname is required. Graphic user interfaces (GUIs), such as the IP Telephony Manager device display, appear and assist you in selecting component parameters and targets.

When using the "x" prefix, for any IP Telephony Manager command, only the target IP address or hostname is required. All other parameters are optional.

For example, if you want to make a modem go off hook, you could simply send the following command:

xtcmcmd 192.78.203.68

First, the device display appears, allowing you to select targets for the command. After you select your targets, the Command window appears, allowing you to select and execute the Off Hook command.

[-llogfile]

The filename for the log

If omitted from the command line, messages are sent to the screen by default (handled as stderr).

If using the x prefix, messages are sent to syslog

To send messages to syslog by default, specify "-" (hyphen) in place of logfile ("-l-" can be sent by itself, it doesn’t have to be included in the command line).

The "-l-" command also changes the GUI default log output to stderr.

(-h)

This switch can be used by itself to display the syntax for a given utility.
