Hi Andy,
The library Spirit.ocx cannot to this operation.
You can however program it yourself pretty easily.
The following is taken from the lugnet archive:
Subject: Sending a message to a RCX using a PC

Thanks to many people (Roger Hamlett and
Philippe Possemiers among other), I now have a short VB
program that can send message to the RCX using the IR tower.
I give you the code for your use. I always
use mod 256 to make sure the message was in the right range
[0..256]:
You need an object of type MSComm for the communications,
and I assume the value to send is in the object Text1:
with MSComm1
rem setting
.commport=1
.settings="2400,O,8,1"
rem open the serial port
.portopen=true
rem send wrapper
.output=chr$(&H55)
.output=chr$(&HFF)
.output=chr$(&H0)
rem code for message, and inverted code
.output=chr$(&HF7)
.output=chr$(&H08)
rem content of the message, and inverted content
.output=chr$(val(text1) mod 256)
.output=chr$((val(text1) mod 256) XOR &HFF)
rem checksum value, and inverted checksum
.output=chr$((val(text1)+&HF7) mod 256)
.output=chr$(((val(text1)+&HF7) mod 256 ) XOR &HFF)
rem close port
.portopen=false
end with
that's it.
If the object MScomm is not in your toolbar, you can add
it using ctrl-T. It is a standard component of VB 5.00.
