This first script is for Port9


#!/bin/bash
# Starts Port9 & Ax25ipd with a Unix98 pair.
 echo "Starting Ax25ipd"
 /usr/local/sbin/ax25ipd  > /tmp/unix98
 echo $! > /var/run/ax25ipd.pid
 export PTS9=`tail  -1 /tmp/unix98`

echo "Start Port 9"
#Attach Kiss Device for AXIP
/usr/local/sbin/kissattach -m 256 $PTS9 9 44.128.1.19 >/tmp/ax25-config.tmp
awk '/device/ { print $7 }' /tmp/ax25-config.tmp > /tmp/ax25-config-tmp
read Device < /tmp/ax25-config-tmp

# Check for Device
 if [ -d /proc/sys/net/ax25/$Device ]
    then echo " Port 9 attached to $Device"
       cd /proc/sys/net/ax25/$Device/
       /etc/ax25/Axipparms
       ifconfig $Device netmask 255.255.255.255
    else echo "** Error setting $Device parms**"
 fi
# End 9

The second script is for RF ports....


#!/bin/bash
echo "Start Port 0"

# Attach KISS-device /dev/ttyS0 to Port 0
 /usr/local/sbin/kissattach  $PTS0 0 44.163.128.5 >/tmp/ax25-config.tmp
 awk '/device/ { print $7 }' /tmp/ax25-config.tmp > /tmp/ax25-config-tmp
 read Device < /tmp/ax25-config-tmp

# Install Parameter: P=250, W=10, TX-Delay=50
 /usr/local/sbin/kissparms -p 0 -r 250 -s 10 -l 20 -t 220

# Check for Device
if [ -d /proc/sys/net/ax25/$Device ]
   then cd /proc/sys/net/ax25/$Device/
      /etc/ax25/Lanparms
      ifconfig $Device netmask 255.255.255.0
      echo " Port 0 attached to $Device "
   else echo "** Error setting $Device parms**"
fi
# Port0 (End)

The Mkiss (in ax25-up) that sets this up is :

echo "Setup Mkiss single port"
# /usr/local/sbin/mkiss -c -s 9600 -x 1  /dev/ttyS0  # Port0
 /usr/local/sbin/mkiss  -s 9600 -x 1 /dev/ttyS0 > /tmp/unix98
  export PTS0=`more /tmp/unix98 | grep -w /dev | cut -b -10`
#  echo "$PTS0"

     or

echo "Installing MKISS for Ports 0 & 1"
#  /usr/local/sbin/mkiss -s 19200 -l -c /dev/ttyS0 /dev/ptyp0 /dev/ptyp1
 /usr/local/sbin/mkiss -s 19200 -c -x 2 /dev/ttyS0 > /tmp/unix98
 export PTS0=`more /tmp/unix98 | grep -w /dev | cut -b -11`
# echo "$PTS0"
 export PTS1=`more /tmp/unix98 | grep -w /dev | cut -b 12-`
# echo "$PTS1"
