Transparent Polled Async
The Transparent Polled Async (TPA) software option supports various asynchronous
protocols that operate in polled environments. TPA allows complete asynchronous
messages to be transmitted without the intercharacter delay normally encountered
when using the standard asynchronous PAD.
The Transparent Polled Async option is available on PathBuilder S200 series switch
platforms.
You may have to access TPA by using either a Custom Software Key (CSK). This is
provided with your option and is recognized only by the specific product for which it
is made. To enter a CSK:
Step
1 Select Configure from the Main menu.
2 Select Software Key Table from the Configure menu. The Entry Number
field is provided for reference purposes in the event you later need to
change or update a specific option.
3 Assign an Entry Number and press Return.
4 Enter the key number in the Key Value field and press Return.
5 Press Escape to exit from the Software Key Table.
6 Save the information when prompted.
For more information about these keys, refer to the Configuration Basics Guide.
