Hello,
Since I had problems with XON/XOFF flow control, I finally tried RTS/CTS
(System Release 2.0 / 68040). After making the correct cable (man zs(4))
I tried my modem connection with cufa. To be sure, I inserted a breakout
box and interrupted CTS. Now no data should be send by the NeXT, but I could
type and got echo from the remote host.
Have I to set special flags in Kermit or Tip or is the handling of RTS/CTS
done by the hardware or driver ?
And what does the following note mean:

<nextdev/zsreg.h>

 * NOTE: the sense of CTS is dependent on the cpu board rev

?

Are there different 68040 boards?

j.k.
