I can't help you with the outboard monitor, but I can help with the haywire / mouse situation.

Windows thinks that the serial port has a mouse connected because of the 1 / second transmissions from the T-Bolt.  At boot time Win looks for serial mice and it gets fooled by seeing something active on that COM port.  There was an answer about this issue from Nov. 1, 2010.

Easy fix. Add the following to your "Boot.ini" file. Obviously, the "x" stands for the COM port you are using.

NoSerialMice:COMx

==========================

This didn't always work for me.  Another way to get it to stop using the mouse is to boot, let it find the "mouse", and then disable it in the Device Manager.  After opening Device Manager you'll find a mouse that doesn't belong there connected to whatever COM port your serial adapter was assigned.  If you move the adapter to a different USB port you'll need to do the process again.

I have been following this on the list for a while now and was curious 
if anyone is actively working on a open source monitor.  I see the one 
made by Adam VK4GHZ is no longer being sold.  This got me back on track 
for wanting to make one of my own.

I have been using either tbmon or lady heather but always have issues 
with a usb to serial converter when I start the computer.  It will go 
haywire and cause it to freeze and make the mouse malfunction.  Once I 
disconnect the converter (I have tried other makes as well) it works 
fine.  Usually I can reconnect the converter and things will work again.

What I would like to do is make a 2 or 4 line lcd readout to display 
various info.  I really liked VK4GHZ's page type selector knob.  I can 
see that being very useful.  On a youtube video by n6vmo said the 
thunderbolt used a ASCII Hex and "needs to be converted by using 64 bit 
floating point math".

So are any of you currently working on this or have decided to quit and 
have any information to share?
