contain space characters (0x20), nor can the first cha-
racter be a decimal (0x2E). A server IP or URL is deleted
by entering 0.0.0.0. For additional information refer to
the section Menu: Setup SYSTEM r Setup TCP/IP r DNS-

Opening the TCP connection
After saving the connection data the Com-Server waits to re-
ceive any serial character. This is the trigger for opening the
connection and is sent to the TCP server together with the
following data.
Alternately the connection can also be triggered via hardware
depending on the status of a handshake input on the serial
port (CTS or DSR). Details can be found in section Handshake
modes r Special r Pin: CTS and Pin: DSR.
