I have a CLI application for which keyboard input has unexpeted
resultd. When I type a leter it does not appear but somethig else
happens. My question is how to distinguish a bug in the application
from problems with my operating system (Devuan daelalus with no
desktop environment). Is there a way to test CLI keybiding?

The text-based applicaton is lifelines, which reads from and wrotes to
a GEDCOM datebase. I installed three slightly different versions of
the application and compiled one from source, although none are the
old version I used to use wihout problem. I have not been able to get
it.

This application presents fields in which to type input. In one
field, when I type a letter instead of appearing it seems instead to
remove the carriage return so that the next field becomes appended to
the field I'm working on. In anther field when I type a letter the
pointer simply jumps to the begining of the label of that field.

This occur in four different installations of Devuan, although all are
daedalus. It there any way I can determine in which direction I should
go?
