I set ixon/ixany, and I have XOFF set in the terminal firmware to 64.

Still no joy.

Well, I sometimes do have rows and columns. That's not the problem
though. Still no joy.

Interesting that you have so many differences from mine. Did you
do anything to change your stty settings or mess with the terminal
definition in /etc/gettytab?

If you are doing nothing special to your system, then why is mine
booting up so different?

Thanks for the info, I'll play around a bit more.  I set the 
newline/carriage return controls I thought should be right
but they seem to have no effect.
