Resetting the counters in Net

Hi folks,
Is there a way to reset the transmit counters in a Net.arcnet driver without
restarting it ?

Hi again,
Actually, I should be a bit more specific… we’re running QNX Proc 4.22B
with:
Net.arcnet V4.22A
Net V4.20D
I expect there are probably updated versions of these but this is a running
system that I would rather not change software in.
I will be surprised if there isn’t a message I can send to Net.arcnet to
reset the counters…

The counters are in the driver, so the only way to reset them is to restart
the driver.

Which counters specifically do you want to reset?

Specifically,
txd_ok.
Our customer has some software that uses that as a basis for determining
that the card/Net is a alive.
It’s currently pegged at 2,000,000,000

Well, I was going to suggest that if the location of that counter was
known (I don’t have a build of that version of that driver handy), then
you could construct a far pointer into Net.arcnet’s data section via the
GDT, and wack the value directly.

Thanks Adam,
I was thinking of that as a last resort.
…strange that there isn’t a message interface to reset this.

I think it’s stranger that they cap off. Then again, using the txd_ok
counter as determination if Net/nic is “alive” wouldn’t have been my
first choice either.

I think directly wacking the counter is your only solution given your
restriction of not changing system software.
