I can't really speak to most of your difficulties, but the serial port
question intrigues me.

I think you mentioned you're using a GENERIC #47 kernel. I don't
remember exactly which kernel this is, but there was a bug in the
1.1 serial code.

To see if you have the bug, type

stty -f /dev/tty01 57600
stty -f /dev/tty01 -e

(this uses the printer port; use tty00 if you're logged in over the printer)

If the baud rate is 61200 or something like that (not 57600) then you
have the broken serial drivers. Well, they work, but you have to scale
your requested speed by 1.0625. This difference only matters at 9600
and below. Ask for 10200 and you get 9600.

This bug has been fixed and is independent of the computer speed-up.

Let me know if this is not your problem.

Take care,

Bill
