Parameter
response-timer { response-timer }
pack-timer { pack-timer }

To configure the raw socket protocol for a serial port, do the following:
116
Description
Synopsis: An integer between 50 and 1000
Default: 100
The maximum time from the last transmitted character of the
outgoing poll until the first character of the response. If the RTU
does not respond in this time, the poll will have been considered
failed.
Synopsis: An integer between 5 and 1000
Default: 1000
The maximum allowable time to wait for a response to a Modbus
request to complete once it has started.
Synopsis: An integer between 0 and 1000
Default: 0
The amount of delay (if any) to insert after the transmissions of
Modbus broadcast messages out the serial port.
Synopsis: An integer between 0 and 2
Default: 0
The number of times to retransmit the request to the RTU before
giving up.
Synopsis: An integer between 1 and 32
Default: 1
The maximum number of incoming connections.
Default: 502
The alternate local TCP port number. If this field is configured, a
single connection (per serial port) may be made to this alternate
port number. Note that Modbus TCP uses a default local port
number of 502. There is no limit imposed on the number of
connections to the default TCP port.
Synopsis: A string
The ID of the RTU(s) connected to the serial port. Specify
multiple RTUs with a space (e.g. 1 2 3 4) or a comma and space
(e.g. 1, 2, 3, 4). A strictly comma-separated list (e.g. 1,2,3,4) is
not permitted.
