lcdvc(1) LCDproc suite lcdvc(1) NAME
lcdvc - LCDproc virtual console SYNOPSIS
lcdvc [-fh] [-a addr] [-c file] [-p port] [-r level] [-s bool] DESCRIPTION
This program shows content from a system console on a LCD controlled by LCDd. As the console is usually larger than a LCD, the area shown on the LCD screen can be scrolled using keys attached to the display. Additionally it has an autoscroll feature, which is on by default and can only be disabled by using lcdvc's menu. By default it uses /dev/vcs and /dev/vcsa devices as the console to show. Other console devices can be set in the configuration file /etc/lcdvc.conf. The keys used for scrolling can be set in the config file as well. OPTIONS
The following options can be set in the configuration file /etc/lcdvc.conf as well, but those given on the command line take precedence: -a addr DNS name or IP address of the LCDd server (default localhost). -c file Specify configuration file. -f Run in foreground. -h Output help and exit. -p port Port of the LCDd server (default 13666). -r level Set reporting level (0-5, default: 2) -s bool Report to syslog (1) or stderr (0, default).
