Hi,

A nice discussion ;)
The forth text interpreter in amforth is line based. This is
coded in QUIT as follows (simplified)
: quit ( stack setup )
[ \ turn on interpret state
begin
( some prompt magic)
refill ['] inte
Hi Matthias,
Does REFILL load a single line?
In a multiline colon definition is it called for each line?
If so I think the best place to handle XON/XOFF is QUIT itself.
At the begin of the loop after calling REFILL assert XOFF and before closing
the loop assert XON.
That way transmission is blocke
I apologize Matthias,
Your solution is ok.
Managing flow control inside REFILL is the same of my proposal and is a better
implementation.

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
Hi Michael,
The Matthias implementation handles flow control once for each line.
That's ok for me.
Perhaps XON XOFF are not the right names... The goal is to manage a ready/busy
flag.
The canonical SW flow control might work different but also the echo control is
not a standard.
Using both of the
Good luck for your project.
