This PR adds
FW_INPUTCHAR
andFW_CHECKINPUT
(as well as their ..._C
variants for symmetry) and blocks onFW_INPUTCHAR
right before warmboot at the end ofdebug_stub
.With the second commit in the PR, there is a loop with
FW_CHECKINPUT
andFW_INPUTCHAR
to clear the input buffer of pending characters before blocking with a finalFW_INPUTCHAR
.This fixes #459.
