# Regression test for PR 20494 (User input stops being echoed in CLI).
# Before that bug was fixed, starting an inferior in a non-main UI
# would result in GDB saving readline's prepped terminal state as
# gdb's "own" terminal state (i.e., target_terminal_ours state),
# resulting in subsequent synchronous execution commands in the main
# UI disabling input echo.

# on the main UI after the synchronous execution command. We test
# with both main and extra UIs as driver consoles for completeness.
