# This script is provided in hopes that it will be useful to
# Technologic Systems customers.  There are no guarantees or 
# warranties.  It was lightly tested using the Debian Sarge
# distribution which is provided in the default, factory software 
# load for the TS-7800.  Also, the TS-CAN1 PC/104 peripheral had 
# JP4 ON, all others OFF.
#
# Here is an overview of what this script actually does:
#
#    1.) Determine if the proper binaries are installed.  If not, 
#        automatically download and install them.  You will need to 
#        ensure the Ethernet cable is connected.
#    2.) Ensure that the PC/104 bus is ON.
#    3.) Insert/install the driver into the running kernel.
#    4.) Ensure that the /bin-utils/ directory is in $PATH.
#    5.) Run the 'sendburst' utility as a demonstration.
#
# Feel free to use this script in your own application and/or modify
# it to fit.  Also, keep in mind that this can be included in the 
# Debian init/runlevel scripts so it loads automatically when the 
# board boots.  Refer to the following resource for more information:
# http://www.embeddedarm.com/about/resource.php?item=410#runonbootup
#
# Also, you may need to ensure that the script has executable rights
# by using the command: chmod +x ts-can1-7800
