Guys, after a lot of help coming from Australia (thank you Hal and Kit) there is a stable version of my Z38XX utility available. It handles the Z3801, the Z3805, the Z3815 and the GCRU. It is available from the usual place. Enjoy! Ulrich Bangert www.ulrich-bangert.de Ortholzer Weg 1 27243 Gross Ippener
