Option–0B = This parameter defines the Poll period or the minimum delay
between polls for a Primitive response. The delay is used to space
out polls after the initial delayed poll specified by the poll delay
option. The value is in milliseconds and ranges from 0 to 5,000
(0000 hex to 1388 hex) in increments of 10 ms. If a value is
specified that is not an increment of 10 ms, it will be rounded
down to the next lower increment of 10. The default is 40 ms.
Option–0C = This parameter defines the maximum poll time or the
maximum amount of time the Network Manager will poll for a
Primitive response before issuing an error message. The time is
measured from the secondary acknowledgement of the received
Primitive request. The value is in milliseconds and ranges from 0
to 40,000 (0000 hex to 9C40 hex) in increments of 10 ms. If a value
is specified that is not an increment of 10 ms, it will be rounded
down to the next lower increment of 10. The default is 10,000 ms.
