LUUP Start Up Code to set serial port

If I power cycle my Vera Plus it forgets the serial port settings which disables my connection (via AD2USB adapter) to my home alarm.

I wanted to write a couple lines of LUUP and set it as a boot up script to run at startup.

Can you control the serial port paramters via LUUP? If so any hints on the commands needed?

I need to set the serial port baud rate to 115,200 and the used by device to “A Vista Alarm Panel” which is device 126 in my system…
