Hi
I assume you mean the interface to the display. I used the winamp wiring 
method.
I also want to note that when i compile lcdproc on my laptop which does 
not even have a parallel port and using an LCDd.conf which is changed 
only so that the driver is hd44780 rather then curses it does the exact 
same thing. Using that kind of LCDd.conf does the same as well on my 
desktop server.

# LCDd.conf
#
# This file contains the configuration for the LCDd server.
#
# The format is ini-file-like. It is divided into sections that start at
# markers that look like [section]. Comments are all line-based comments,
# and are lines that start with '#' or ';'.
#
# The server has a 'central' section named [server]. For the menu there is
# a section called [menu]. Further each driver has a section which
# defines how the driver acts.
#
# The drivers are activated by specifiying them in a driver= line in the
# server section, like:
#
#   Driver=curses
#
# This tells LCDd to use the curses driver.
# The first driver that is loaded and is capable of output defines the
# size of the display. The default driver to use is curses.
# If -d is specified on the command line, the Driver= options in the
# config file are ignored.
#
# The drivers read their own options from the respective sections.

## Server section with all kinds of settings for the LCDd server ##
[server]

# Tells the server to load the given drivers. Multiple lines can be given.
# The name of the driver is exactly the same as the name of the driver
# module that is to be loaded, including the case of the letters !
# (That is: unless a file= option is given in the driver section)
#Driver=CFontzPacket
Driver=hd44780
Driver=joy
#Driver=MtxOrb
#Driver=CFontz633
#Driver=CwLnx
#Driver=glcdlib
#Driver=imon
#Driver=NoritakeVFD
#Driver=serialVFD

# Tells the driver to bind to the given interface
Bind=127.0.0.1

# Listen on this specified port; defaults to 13666.
Port=13666

# Sets the reporting level; defaults to 2 (warnings and errors only).
#ReportLevel=3

# Should we report to syslog instead of stderr ? Default: no
#ReportToSyslog=yes

# Sets the default time in seconds to displays a screen.
WaitTime=5

# User to run as.  LCDd will drop its root priviledges,
# if any, and run as this user instead.
User=nobody

# If yes, the the serverscreen will be rotated as a usual info screen. 
If no,
# it will be a background screen, only visible when no other screens are
# active.
ServerScreen=no

# The server will stay in the foreground if set to true.
#Foreground=no

# Where can we find the driver modules ?
# IMPORTANT: Make sure to change this setting to reflect your
#            specific setup! Otherwise LCDd won't be able to find
#            the driver modules and will thus not be able to
#            function properly.
# NOTE: Always place a slash as last character !
DriverPath=/usr/local/lib/lcdproc/

# The "...Key=" lines define what the server does with keypresses that
# don't go to any client.
# These are the defaults:
ToggleRotateKey=Escape
PrevScreenKey=Left
NextScreenKey=Right
ScrollUpKey=Up
ScrollDownKey=Down

# If you have only 4 keys, you can choose to use this:
#ToggleRotateKey=Enter
#PrevScreenKey=Left
#NextScreenKey=Right

# If you have only 3 keys, you can choose to use this:
#ToggleRotateKey=Enter
#PrevScreenKey=Up

## The menu section. The menu is an internal LCDproc client. ##
[menu]
# You can configure what keys the menu should use. Note that the MenuKey
# will be reserved exclusively, the others work in shared mode.

# The following works excellent with 4 keys or more.
MenuKey=Enter
EnterKey=Escape
UpKey=Up
DownKey=Down
# If you have 6 keys you may define these as well
LeftKey=Left
RightKey=Right

# If you have only 3 keys, you could use something like this:
#MenuKey=Escape
#EnterKey=Enter
#DownKey=Down
