This just might explain a problem I am having with a VB program.
After a while my battery meter function stops getting a reply from
the RCX. It calls the RCX every 10 secs from a Timer control
event. Then all of a sudden, while the RCX is still on and doing
things, the VB program can't get a response. When this has
happened, even a ALiveOrNot call doesn't get a response.
However, motor control commands do get sent to the RCX because
the RCX does what it was told to do.
The only way I could get back return values from the RCX when this
has occurred, is to restart my VB program. Then all is well even
without switching the RCX off and on.
