17.3 OS/2 KEEPALIVE configuration
The TCP/IP "inetcfg" command can be used to configure the
"KEEPALIVE" parameter.
"KEEPALIVE" parameter.
inetcfg KEEPALIVE=nnn
where nnn is the number of minutes a TCP connection must remain
inactive before TCP generates a KEEPALIVE transmission for an
application that requests them.
Default is 120 minutes.
inactive before TCP generates a KEEPALIVE transmission for an
application that requests them.
Default is 120 minutes.
The inetcfg command must be run each time the OS/2 system is started.
Adding the inetcfg command to \tcpip\bin\tcpstart.cmd is a convenient way
of automating this step.
Adding the inetcfg command to \tcpip\bin\tcpstart.cmd is a convenient way
of automating this step.
Adding, e.g.
inetcfg KEEPALIVE=4
to \tcpip\bin\tcpstart.cmd causes TCP to send a KEEPALIVE transmission
if a TCP connection has been inactive for 4 minutes and the application
requested KEEPALIVE transmissions, as OS/2 now does. OS/2
recommends this TCP configuration setting to customers who use TCP/IP
attached printers and the device.

If the KEEPALIVE transmission is not acknowledged, the TCP will attempt
to re-connect up to 9 times. The interval between these attempts is fixed
but short.
