# This script is for use with the uIP test programs and AtariSIO.
# Before running this, run "make disk" to create the disk image.
# This script needs to be run with root privileges (e.g. with sudo)
# Configurable stuff:
ATR_IMAGE=${1-fujichat.atr}
#ATR_IMAGE=fujitest.atr # Name of the disk image
TTY=/dev/ttyS0 # serial port to use
BAUD=4800 # must match compiled-in value in rs232dev.c
SLATTACH=a8_slattach # slattach binary (possibly patched)
SLIP_IFACE=sl0 # probably no need to change this
LOCAL_IP=192.168.0.1 # SLIP IP address for Linux host
REMOTE_IP=192.168.0.2 # SLIP IP address for Atari host
IP_FORWARD=yes # Route packets for the Atari?
IP_MASQUERADE=yes # NAT for the Atari?
MASQ_IFACE=ra0 # if NATing, our main (LAM or internet) interface
DUMP_PACKETS=yes # Run tcpdump on sl0 interface?
# DELAY is needed on some (most?) systems because e.g. atariserver tries
# to run before the atarisio module is fully initialized. Choose one:
# No delay:
#DELAY="true"
# 1 second:
#DELAY="sleep 1"
# 1/4 second (may not work on old Linux installs):
DELAY="usleep 250000"
# End of config section, start of code:
