[Xastir] Pointers please

[ml41782]

I'm looking for guidance or evern a script to finalize my system in the event of 
a power failure. I have been very lucky that my system hasn't gone down on its 
own and tried to come back up. I'm running 3 radios on the system  all under 
ax25. 


I have a KPC3 connected directly to ttyS0 
and a KPC9612 connected to /dev/ttyUSB0
if I reboot I run through this ritual to restart xastir & digi_ned

sudo  mkiss -s 9600 -x 2 /dev/ttyUSB0 
sudo /usr/sbin/kissattach /dev/pts/3 2 172.1.1.1
sudo /usr/sbin/kissattach /dev/pts/4 3 172.1.1.1
sudo /usr/sbin/kissattach /dev/ttyS0 1 10.2.2.2

The only thing that has stopped me from putting this into a batch file is the 
/dev/pts 

depending on the reboot I can get /dev/pts/  1 & 2 or 2 & 3. 
How can I script this properly to do this all behind the scene ? 

Thank you for any help in advance. 

Mike
