Follow-up Comment #1, bug #52248 (project screen): I have just encountered this exact same issue. The symptoms are incredibly mysterious.
This happens only with screen. Other tools (picocom, cu) do not enable exclusive locking on the PTY, so they work ok. After connecting to the PTY with screen, other tools stop working as well. _______________________________________________________ Reply to this item at: <https://savannah.gnu.org/bugs/?52248> _______________________________________________ Message sent via Savannah https://savannah.gnu.org/
