10.2.5 Application:
Client/Server mode between Com-Server-Ports
There are various ways of connecting two or more Com-Server
ports together in this mode. All involved Com-Server ports
must be configured for TCP client mode and may then
alternately connect to each other when there are data on the
serial port. After the data has been send the connection is
closed either by the
Inactivity Timeout or the Disconnect
Character .
When the clients have changing IP addresses, for example in
the case of connections via DSL routers with NAT, alternating
operation of the Com-Servers in TCP client mode can also be
used as an alternative to Box-to-Box mode. Under
Server IP/URL
the host name of the counterpart is used instead of the
numerical IP address. In this case the Com-Server obtains the
current IP address first via DNS before the TCP connection is
opened. Updating of the DNS system when there is an IP
address change must be done by the DSL router itself or by
another component with appropriate client service (e.g.
DynDNS).
