bbhosts TIMEOUT tag

Hi friends,

I've seen on the bb-hosts example file on www.hswn.dk/hobbit/ the line:

0.0.0.0 osiris.hswn.dk # dialup CLIENT:osiris DOWNTIME=*:2300:2359,*:0000:0800 NOPROPRED:procs TIMEOUT:4:9

Does someone know what this tag "TIMEOUT:4:9 " do? What version of xymon?

Thanks in advance,

Mario.
