Tums

Peter, Thanks have been doing that.

Jam1e1, have tried 2 different cables, maybe I need to spend more and buy a decent one . will the operating system make a difference???. Thanks for the reply.

Can anyone tell me about updating the handset firmware please.

I have downloaded the relevant files from SW, put them in a separate folder on my desktop. bought a USB to Serial cable.

I can get the Loader up and put the update file in it.

But when I click update or hc version, it pops up straight away telling me it can't find the handset. I've tried on a Windows 8.1 computer and a windows 7 netbook. both do the same error.

is it necessary to update the handset?? or should I just leave it as is???.

Thanks on advance for any suggestions.
