Hi,
It looks like you really meant a single "byte".
To my understanding from the RCX 2.0 (with usb port) SDK available from
Lego, the "byte" would have to be wrapped up in a certain way, such as
leading sync bytes plus a number of conditions to form a command for
transporting through the IR tower.
For example the "byte" itself must have a certain bit toggled between
commands, followed by the compliment of the "byte". The "byte" also
implies the number of bytes of parameters to follow. The parameters
should then be paired up with their compliments in the same way. At the
end there should be a sumcheck and its compliment.
It is a command in a proper wrapper, the RCX is looking for. We cannot
expect the RCX to respond to a single byte in isolation.
There is a send raw command in nqc, you can send raw bytes to send but
again the RCX would only respond unless it is a properly formed dcommand.
Please read the documentation in the RCX 2.0 SDK for details. It
should be the same for RCX 1.5, since there isn't a separate SDK for RCX
1.5.
By the way, if you are using nqc (Not Quite C. It is free!), you may
try the undocumented -v option. It shows you how each command is being
sent and responsed to. In that way you can learn how the wrapper works
so that you can do the same in your SENDBYTE.
P.C.
