dll - A user-program downloader for the RCX.
Contents
Commands
-d{1-8},--delete={1-8}
Delete program from program-slot-number {1-8}
-n{hostaddress},--node={hostaddress}
Set RCX LNP host address to {0-15}
Description
This manual page documents the dll user-program download command.
dll is a program which is used to download user programs written for brickOS to the RCX.
Environment Variables
dll will respond to the environment variable RCXTTY. This should be set to the serial device to which
the IR tower is connected. Use of RCXTTY is equivalent the using the -tty command-line option.
Error Messages
Unfortunately, there is basically only one dll error message, and it applies to most possible errors,
including a disconnected IR tower, an RCX that is turned off, an RCX that doesn't have brickOS, and an
RCX that has brickOS and is already running a program. So, check all those things when dll fails.
Examples
dll is a simple command to use. The following examples show most of the uses.
Ex1: download demo/robots.lx to the RCX as program 0.
$ dll -tty=/dev/ttyS0 demo/robots.lx
$
NOTE: there is no response from dll(1) on a successful download. You can, however watch the RCX display
during the download and see activity.
Ex2: download the demo/linetrack.lx into program-slot 7. (note we are first setting RCXTTY so we don't
have to keep specifying the tty device each download).
$ export RCXTTY=/dev/ttyS1
$ dll -p7 demo/linetrack.lx
$
Ex3: download demo/rover.lx but we are leaving the RCX powered off (assume RCXTTY is already set).
$ dll -p2 demo/rover.lx
error deleting program
$
NOTE: dll first deletes the existing program from the specified program slot and then downloads the new
one. This error indicates that the first thing dll tried to do did not succeed.
We'll leave the experiment of running dll with --verbose set as an exercise for you our reader... (This
is actually a combination of progress information and debug output.)
