Hi,
I'm attempting to use rdbfs to debug my CPU server via my diskless
terminal. The main problem (I'm sure there will be others) is that my
serial line seems to be hung up. I get no data in either direction after
^T^TD.
I run the typical:
rdbfs -p 999
acid -k 999 /path/to/kernel
(the above is typed on the term prior to ^T^TD on the CPU)
I also tried:
echo b9600 > '#t/eia0ctl'
on both ends before attempting to use rdbfs.
Any ideas?
Don

Do you have console=0 in your plan9.ini?

Yea, I'm a complete maroon. I forgot all about that. I misinterpreted
the manual which says "plan9 automatically initializes serial devices
on boot" into thinking it meant "this automatically gives you a
console".
Thanks,

The remote debugger really should tell you when
there is no console. It's a bug that it doesn't.
