Okay - I have had a response from Roy at Phaedrus and I have done some
more testing with the counters.
First - I have found that the BSC command does work for setting the
counter, eg.
xap-header
{
v=12
hop=1
uid=FF411100
class=xAPBSC.cmd
source=mi4.homeseer.dpjukebox.Master
target=phaedrus.netiom.location:counter.9
}
counter.state.1
{
id=39
level=900
}
Roy has responded re the counter overflow with the following comments:
"Handling a counter overflow always causes problems. We can do one of
3
things:
1. Freeze the counter at the upper limit. This is OK but if an
application is looking for a change without checking for the upper
boundary then it can prevent it from functioning correctly.
2. Reset to zero. In this case the monitoring application could get
confused in any number of ways.
3. Allow the counter to overflow, in this case it will return a negative
value. This has two main advantages. It imeadiately indicates that there
has been an overflow and because it is done in a defined manner it
allows the application to derive the amount by which the counter has
overflowed.
As with anything of this nature it is better for the application to
monitor and maintain the couters inteligently, applying a reset as soon
as the counter nears its overflow level."
A reasonable response indicating that the overflow is probably planned.
If we think the counters should react differently then we should come up
with an appropriate response. I think I am reasonably happy with this
approach but would be interested in any other ideas.

I don't believe you can switch off individual node events.
The following command will set the counter to 0. You can actually set to
any acceptable value.
xap-header
{
v=12
hop=1
uid=FF411100
class=netiom.cmd
source=mi4.homeseer.dpjukebox.Master
target=phaedrus.netiom.location
}
counters.state
{
counter.1=0
}
