There is no user intervention here once the ratio is set. Setting the ratio
enables this operation. Use the send.exe command to send
CONFigGbxxyyFFFF command where xx is the number of good
packets to be required and yy is the number of bad (unacknowledged)
packets to be tolerated. Whichever threshold is reached first will reset
the count of both good and bad packets and will take an action: either to
turn off collisions, leave them off, turn on collisions or leave them on.
So if the following entry is made: send CONFigGb0F1dFFFF <ret>
then when 15 good packets are reached before 30 bad packets, the
collisions will remain on. If not they are turned off. The ratio is 0.5 and
the absolute numbers used reflects the reaction time. In this example,
15 packets are the minimum time to make a determination. The four
0xFs at the end of the command allow the user to have hysterises.
Unless the user fully understands the use of this part of the command, it
is recommended that these be left as 0xF (they must be entered). In the
case of entering CONFigGbxxyywwzz, xx is only the number of good
packets required to reset the bad-packet count that turns the collisions
off. And yy is the number of bad packets required to turn the collisions
off. ww is the number of good packets required to turn the collisions
back on and zz is the number of bad packets required to reset the good-
packet count that would be used to turn the collisions back on. By
making these four parameters independent, the user can set one ratio for
the collisions to turn off (xx/yy) and another for the collisions to turn
back on (ww/zz) with the absolute values of each setting the
approximate reaction time measured in packets. Resetting the good and
bad values to 0xFF (i.e. CONFigGbFFFFFFFF) turns the function off,
which will leave flow control always on (assuming that the
configuration bit for AUI collisions is set).

Another feature of the M10II is the use of remote commands. A M10II
will respond to most configuration commands over the air. Use the
SendM10 utility but address the destination of the command to the
MAC ID of the remote M10II (i.e. 00606Fxxxxxx). Even if the remote
radio is set to use the Clarion null address instead of its own MAC ID,
the radio’s MAC ID must be used for remote access. To allow a
broadcast address to be used over the air would require handling
multiple responses, which is not possible. The command will
automatically flow through the sending M10II to the remote M10II and
the response will occur back throughout the sending M10II. The re-
transmission protocol will also work as in the case of any normal
packet. Remote M10IIs can be queried, and reconfigured. Using
Tmshow, you can view the remote M10II’s table entries. For security
