Re: [Flashforth-devel] Xon/Xoff how to

[Herman A. <exp...@vn...>]

Mikael,

My thoughts with XON/XOFF topic come from experience of the earlier FF 
versions.
Thoroughgoing testing the FF5.0 with SW-FC, the trouble seems not a 
simple delay problem.
Using #define FC_TYPE_SW ENABLE in p18f-main.cfg the FF5.0 does not 
send or receive
XON/XOFF characters in any direction. I think so, it works without any 
flow control.
Maybe I failed, but please check it. I used 18F46K22@64MHz in test.
The HW-FC works fine.
