d. (Optional) Enable the gateway to send broadcast messages to this client:
(config service modbus_gateway client test_modbus_client)> broadcast
true
(config service modbus_gateway client test_modbus_client)>
e. Set the maximum time to wait for a response to a message:
(config service modbus_gateway client test_modbus_client)> response_
timeout value
(config service modbus_gateway client test_modbus_client)>
Allowed values are between 1 millisecond and 700 milliseconds, and take the format
numberms.
For example, to set response_timeout to 100 milliseconds:
(config service modbus_gateway client test_modbus_client)> response_
timeout 100ms
(config service modbus_gateway client test_modbus_client)>
The default is 700ms.
f. Configure the address filter:
This filter is used by the gateway to determine if a message should be forwarded to a
destination device. If the Modbus address in the message matches one or more of the
filters, the message is forwarded. If it does not match the filters, the message is not
forwarded. Allowed values are 1 through 255 or a hyphen-separated range.
For example:

(config service modbus_gateway client test_modbus_client)>
where value is either rtu or ascii. The default is rtu.
iii. Set the maximum allowable time between bytes in a packet:
(config service modbus_gateway client test_modbus_client)>
serial idle_gap value
(config service modbus_gateway client test_modbus_client)>
where value is any number between 10 milliseconds and one second, and take
the format number{ms|s}.
For example, to set idle_gap to one second, enter 1000ms or 1s.

(config service modbus_gateway client test_modbus_client)>
