Hi there,

the solution was rather simple: have a shell script that counts the xlog 
file lines and adds 599000:


#! /bin/bash 
echo $(echo "599000 +" $(cat /home/daniel/.xlog/test.xlog | wc -l) | bc)

And run $(/fullpath/serial.sh) in a gmfsk macro.

Of course, that is very crude. I should not hardwire the RST. And allow 
for the case that the serial number has 4 digits or more. And of course, I 
shouldn't use a work-around, but use the internal communication channels 
between xlog and gmfsk. But the contests starts in a few hours...
