imonlcd v0.2


News

New version of imonlcd released. v0.2 now supports full client/server handshaking according to LCDproc protocol: fixes "Broken pipe" errors issued by LCDd trying to get imonlcds attention. Added -v command line option for verbose output. Revised code to update ISDN status infos from /dev/isdninfo. All required sources are now include in the imonlcd distribution.



Overview

imonlcd is a LCDproc client program for Linux that displays the current line status of ISDN4Linux devices.

Requirements

You need a working LCDproc server and suitable LCD Module (eg. Matrix Orbital LK204-25). If you've never heard of LCDproc find out more here before you read any further.

LCDproc ver0.4-pre6 and imonlcd were compiled and tested on Linux 2.0.36 and the isdn4linux subsystem that comes with the kernel source tree, Rev: 1.44.2.9/1.41.2.11/1.48.2.27/1.28.2.2/1.8.2.2. Since imonlcd derived from imontty the same restrictions apply. To put it another way: if imontty works for you imonlcd should as well. ;)

Installation

Unpack the imonlcd distribution. Run make and install the imonlcd binary wherever you want.
Makefile options: PRIORITY defines the screen priority for imonlcd if a ISDN channel is busy, see LCDproc docs for details. Defining DEBUG will produce detailed output on STDERR about the actual messages received from and send to LCDproc by imonlcd.

Operation

Be sure you have a running LCDd and start imonlcd. You can set a different server (default localhost) and port (default 13666) using -s <server> and -p <port> on the command line. Verbose output can be turned on using -v.

Eventually you'll see the imonlcd 'idle' screen on your LCD:

An ISDN call to your provider will set the screen to:

If somebody calls you and the remote party sends a caller ID, you'll see the following before you pick up the phone:

PLEASE NOTE: imonlcd is limited to display only outgoing calls initiated by ISDN hardware managed by an isdn4linux driver in your PC. Like imontty it uses /dev/isdninfo to gather information about the current status of your ISDN devices. Outgoing calls from analog phones/modems (connected to your local ISDN S0-Bus using somekind of A/D-ISDN unit) or other native ISDN equipment (telephones, fax machines) will not show up on the imonlcd screen.
