Poll and Select Timeout
This is the time, in milliseconds, the controller waits for a response to either a Poll

The values for this parameter are in 10-millisecond increments. A value that is not
a factor of 10 rounds down to the nearest 10-millisecond factor.
Example: A value of 305 rounds down to 300 milliseconds.
The selections are 0 to 655350, 300.
Activity Timer
Activity timer is the time, in minutes, that no data can be present on the port
before the unit disconnects the line. This is used primarily in dial-up applications.
Line disconnection is done by lowering the DTR signal for 500 milliseconds and
raising it again. Entering 0 disables this feature. The selections are 0 to 255.

This counter is used in conjunction with the Limited Select option on the terminal
address screen. When that option is set to Y, the unit flushes a message after the
Limited Select Count number of NAKed selects. The selections are 1 to 255, 10.
