Got myself a Tiger Learning Computer today

[schmidtd <schmidtd@my-deja.com>]

Today, my shiny new (well, not really shiny or new) Tiger Learning
Computer arrived.  It is just the computer and software cartridges; no
power supply or mouse.  Of note - the cartridges live where the LCD
screen would be if it really were a laptop - which is what it looks
like, but really isn't.

I hooked up a random 9v/350mA wall wart power supply, and up it came.
What I really want to do is to get the serial port talking so I can
move some information back and forth.  From my reading online, the
serial port should be the male DE9 on the back, and is wired to need a
null modem in order to talk to another DTE (like a typical computer on
the other end of a USB/RS-232 dongle).  So far, no luck - PR/IN#2
isn't doing anything like I expect.  The cursor changes a bit, but it
doesn't take Ctrl-A commands, and I don't see anything coming or going
via HyperTerminal (yes yes, a poor indicator of eventual success).

Anyone ever get one of these things talking?  The online resources
talk about a "Com" app, but as far as I can tell... all it does is set
baud/stop bits/parity.
