[Xymon] drop multiple hosts with wildcard

[Kris Springer]

Is there a way to drop all host data for multiple hosts using a 
wildcard?  I know how to drop a single host and erase it's data, but I 
have a long list of IP Cameras that I changed in my hosts file and 
instead of dropping each individual hostname I'd like to drop all hosts 
that start with 'Cam'.  I attempted this but it didn't remove anything.

./xymon 127.0.0.1 "drop Cam*"
