I'm programming the RCX using the Mindstorms RIS software and running into
a problem I can't figure out. My program has about 15-20 TONE commands to try
and play a song. It downloads to the RCX without error, but when I run it it
only plays about the first 8-9 TONEs. If it was memory problem on the RCX end
I would expect the download to give an error. Any ideas on what the problem
is? Also, any rough numbers on how large a program can be downloaded?
I know there are other programming platforms (such as NCQ) available, but
I'm doing this with my 7 year old son and want to stick with the provided
environment.

| Since he can use the tower without *any* problem, my guess is that the problem is not with the COM port, but with the tower itself. To my knowledge no one ever came up with a way to keep the tower alive by software besides sending some data at (...) (25 years ago, 30-Jun-99, to lugnet.robotics)
