  1. [9fans] rdbfs issues

    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.
