By default, MacWise version 16 now uses Kermit for telnet connections when it detects MacOS 10.13 or later.
It also enables two Kermit options by default:
"Use SLnet options for Kermit" and "Echo Kermit Characters"
Not all host servers work properly with those two options.
If you are getting double characters on your screen, then uncheck "Echo Kermit Characters"
If your arrow keys and function keys do not work, then uncheck "Use SLnet options for Kermit"
Note that other factors can cause arrow keys and function keys not to work.
If you cannot log into your host, then put a checkmark on "Use SLnet options for Kermit"
You may see the following errors when opening a connection if it is unchecked:
Negotiations...
The Telnet server is not sending required responses
Telnet waiting for response to WILL KERMIT
Telnet waiting for response to DO KERMIT
