When you are opening a Communications document and get the message "No Terminal tools are available. The document will not be opened."
Verify the following:
There is a VT102, Apple Modem Tool, and Serial Tool, in the Extensions folder, of the System folder of the startup drive. And, there is also a VT320 Keys stationary file in the Stationary folder inside the Claris folder.
This error will occur if any of these files are missing.
