I just use the default of 9600.  You don't want to go much faster for the
Linux console anyway. Poor unbuffered serial port with high-latency Linux
OS (compared to AmigaOS ;-).

When the old hard drive died, I lost my Lilo setup, and settled for "newshell
aux:".  It was already sufficient hard to transfer the data to a newer +4 GiB
hard drive.

when I'm talking to journalists I just say "programmer" or something like that.
