Input split over multiple lines when receiving delayed output

[pengowen123]

Output can be delayed due to confirm dialogues or buffering commands, and when it is eventually received, the currently entered input gets stuck on an old prompt visually (but continues to function normally):

> COMMAND_SETUP
< 01 (RESPONSE_OK)
< 0a (RESPONSE_WAIT_USER_CONFIRM)
// Buffer a command during the confirm dialogue
> ff
> COMMAND_
// `cancel` is pressed on the device here so that the `ff` command can be processed
< ff (RESPONSE_ERROR_UNKNOWN_COMMAND)
> INFO
< 72796465720000050001
>
