I'm interested in other people's experience with various terminal emulators on Linux. I've been using minicom with indifferent results, probably because it doesn't support delays between lines which possibly overruns pbforth's serial input. minicom (...)

Does the prompt handler (CLI) do multitasking? In otherwords if a new task is started and control returns to the CLI will the new task ever run? I think I am asking whether it calls PAUSE in a loop while waiting for user input? (24 years ago, 3-May-00, to lugnet.robotics.rcx.pbforth)
