There is no higher version of ZCL, and Kerry P doesn't love us any more. So,
you you have is what you get, but for the price, it is a super little app. I
don't know the answer to your other questions. I used my Z w/ ZCL to dial in
to a Sperry 5000 and get my email. For this it worked super. I selected
VT-100 emulation and viola! Happy Zoomin'
