Hello,
I've made something like that in java. I've started out with the rcxport of
Scott Lewis (www.slewis.com/rcxport/) and made a little console application
with it that accepts a port identifier and a value as parameters.
It works under Linux and under Win95/98, but you do need the Java Comm API
(http://java.sun.com/products/javacomm/index.html). With Win95/98, you only
need to add the comm.jar to your classpath, but with Linux there are a few more
steps to be taken. If you intend to use it with Linux, let me know and I'll
post the exact instructions.
Under Win95/98, use the following syntax : java -classpath
%classpath%;comm.jar;rcxport.jar rcxport.RCXPortApp name_of_the_port
value_to_send
where name_of_the_port is of course the port where your IR tower is connected
(eg COM1) and the value_to_send is the hexadecimal value of the decimal
message. To be more precise, you decide on a certain value, convert it to it's
hexadecimal value, send that, and in your RCX program you get the decimal value
. So if your RCX program expects 22, send 16.
Here's where you can get the rcxport.jar with everything you need(except the
java Comm API) : http://bewoner.dma.be/rcx/rcxport.jar
Hope this helps...

| Hi, I've seen in Dan Baum's book that the PC can be used to send messages (as if it was itself a RCX) to other RCX. Does anyone knows the procedure? Please send details so that I can myself program this. If you have code lines, that's even better (...) (25 years ago, 17-Jan-00, to lugnet.robotics)
