I have begun a project to communicate with the Lego Mindstorms Rcx
Brick. 
In the next few days I'll get a Web Page up with some rudimentary code. 
Initial goal is to initialize the interface and implement a keep alive
feature to keep the Brick on-line.

Andreas, you posted a message a while ago that indicated some code was
missing to support serial ports properly.  That message was in the
context
of version 2.1.  However, what I am seeing is the the same symptom
reported
in that message.

I am running in to the following trying to open the Serial Port with
Squeak
2.3 beta on Windows 98.  I'm getting a primitiveFailed error on
SerialPort>>#primClosePort: when sending SerialPort>>#openPort: to get
the
port open.

Squeak VM version is 2.0.1.15 1998/11/26.

Andreas, can you help me here?

Thanks - 
Jeff Odell
