I think I should be ok with the RCX program. However, I still wonder
how to send the commands from the PC to the RCX through the serial
connection. The PCs are running under Windows 2000 and the
Mindstorms robots use the usb IR tower.

Does anybody :
    1. knows about a program that would do what I want, ie send a
    string
to the RCX throught the usb IR tower

I have a simple WIN32 console application (with C source code) that
opens the USB tower to listen for messages from the RCX.  You can
easily modify this program (using the WriteFile() API system function)
to talk to the RCX.

It's not exactly what you're asking for, but it might get you started.

I just looked over it, and it seems very near to my needs. I may try to
modify it for writing to the USB tower. Thanks.

By the way, which C++ compiler do you use ?

    2. what are the messages sent by the remote control tool from
BricxCC ?

I have documented the messages that are sent by the Mindstorms IR
remote control, which are probably the same ones used by BricxCC:

That should be. I suppose those are the codes you use in your "Virtual
Remote" program. Am I right ? If so, it would be quite easy for me to
write a RCX program that waits for such messages and performs he right
actions.

The disclaimer only talks about personal use. Would you allow me to use
your piece of software in classroom?


I hope this helps.  Good luck with your class!

It did. Thanks.
