Never forget: xon/xoff is for *single* character exchange - send one, get echo, check it, send another one... Sender must interpret *each* echo character immediately and stop at xoff at once. Use xon/xoff to connect two amforth devices via TXD/RXD. Or on a PC use a sending tool able to do that. amforth shell is such a tool.
If you send ascii to amforth using a terminal emulator on your PC via a USB-serial converter, forget xon/xoff. There will be huge blocks of characters already send to the pipeline of USB, overrunning your forth target, before any terminal emulator will notice the xoff. Or do you have a USB-serial converter that handles xon/xoff ?
