Sounds like you might be dealing with a particular implementation quirk, or perhaps with SSH or some other network transport issue. In general terminal emulators tend to implement control character processing with a state machine: https://vt100.net/emu/dec_ansi_parser https://vt100.net/emu/dec_ansi_parser In theory that shouldn't be affected by latency or delay in processing characters or groups of characters, and should be independent of the line speed, after all, the VT100 was able to operate at speeds between 50bits/second and 19,200 bits/second. https://en.wikipedia.org/wiki/VT100 https://en.wikipedia.org/wiki/VT100 That said, there are so many terminal emulators out there (xterm, gnome-terminal, linux console, just to name a few) and so many potential transport protocols (telnet, SSH, serial etc) and modern pty layers to deal with as well, so there are bound to be differences/quirks with different combinations.
