# Required-Start: checkfs
# Required-Stop: $remote_fs
# Default-Start: S
# Default-Stop: 0 1 6
# Short-Description: controls configuration of serial ports
# Description: Set and/or report the configuration information
# associated with a serial port. This information

### END INIT INFO
# This file uses settings from /etc/serial.conf to configure the serial devices.
# This file only exists if you chose to configure the serial devices
# by hand yourself. Otherwise serial configuration happens later on
# using the /etc/init.d/setserial file.
#

# If the serial executable has been removed abort the configuration
[ -x ${SETSERIAL} ] || exit 0
