p2024[2]: Telegram pause time (pause time between two telegrams).
The following applies for BACnet:
p2024[0]: APDU timeout.
p2024[1, 2]: Not relevant.
Index: [0] = Max. processing time
[1] = Character delay time
[2] = Telegram pause time
Dependency: Refer to: p2020, p2030
Note: For p2024[2] (Modbus):
