For primary, it is the minimum time to be taken
for a cycle round the active poll table; if this
time has not elapsed when the bottom of the poll
table is reached, then polling will pause until
this timer expires. A value of zero means there
will be no pause between cycles round the poll
table.
For secondary, the pause time out is the delay
taken before sending a response to a poll
when it has no data frame to send.
The units are tenths of a second. The default
is 10 (1 second).
