Installation guide

keepalive={on|off}

Indicates whether or not TCP keepalives are sent for the specified range of

clients. If set to on, keepalives are sent, if it is off, keepalives are not sent.

Configurable TCP keepalive parameters, for example, how many

keepalives to send and when to send them, are configured globally via the

“set network” command (see "set network").

nodelay={on|off}

Used to allow unacknowledged or smaller than maximum segment sized

data to be sent.

Note: The “nodelay” option disables Nagle’s algorithm, which is on by

default for some TCP services. Nagle's algorithm reduces the number of

small packets sent. It instructs to hold on to outgoing data when there is

either unacknowledged sent data or there is less than maximum segment

size (typically around 1500 bytes for Ethernet) worth of data to be sent.

While this algorithm keeps transmission efficient, there are times when

disabling it is desirable.

Examples Set autoconnect on with trigger

This example shows setting autoconnect to connect to the TCP port (2101) of

the network IP destination when data arrives on the serial port.

#> set autoconnect state=on trigger=data

ipaddress=10.0.0.1 ipport=2101

Allow outgoing data that is either unacknowledged or less than maximum

segment size

#> set autoconnect port=1 nodelay=on
