Network Delay
In its default setting the Com-Server attempts to sent the seri-
ally arriving data to the network-side application with as little
delay as possible. Particularly when working with host serial
protocols it may be necessary to send the protocol blocks
enclosed in a network packet if possible. The option Network
Delay in Setup Setup Port x r Setup TCP/IP r System Options
allows an artificial delay in transmission for this purpose. De-
tails can be found in section Menu ... Setup TCP/IP r System
Options.

Keep Alive Time
...
The factory default setting for the keep-alive check is 30 se-
conds. I.e. if there is no data traffic the Com-Server checks
during the set time interval to see whether the connected
network application can be reached. If there is no reply, for
example due to a break in the network infrastructure, the
Com-Server resets the connection internally and thus enables
a new connection to be opened. Details can be found in sec-
tion Menu SETUP System r Setup TCP/IP.
