The MS-DOS Kermit behavior is not different from the Kermit 95 behavior.
In order for an APC to be evaluated the command parser must be activated.
There are no restrictions on what can be put in an APC. Therefore, the
command screen must be activated. Otherwise, the user would not be able
to see command output or be able to respond to prompts for input.
If all you want to do is change terminal emulation parameters then there
are most likely escape sequences defined for the terminal emulation that
will do what you desire. An APC would not be necessary for that.

I'm not sure what you are asking here. An APC can include user defined
macros.
As far as 'eval' goes. Simply define a macro to be the commands you want
executed and then call it.
