Description
For example: install terminal emulator software in a guest, and connect it to a serial port that is a tcp server on the host side. Connect to that port with telnet or putty. As you press keys on the telnet side, one would expect them to appear in the guest. They do not, until ENTER (or return) is pressed.
Install BBS software in a guest, associated with a serial port configured similarly. If the software provides a prompt and is awaiting a single keypress, that keypress cannot be received until enter is also pressed.
Note:
See TracTickets
for help on using tickets.
This specific to telnet which operates in LineMode by default, see here. It only sends the data when the user hits enter.
