Following is an overview of some of the services provided by these protocols.
Serial data communication over TCP and UDP
ConnectPort LTS products support serial data communication over TCP and UDP. Key features
include:
 Serial data communication over TCP, also known as autoconnect and tcpserial can
automatically perform the following functions:
– Establish bidirectional TCP connections, known as autoconnections, between the serial device
and a server or other network device. Autoconnections can be made based on data and or
serial hardware signals.
– Control forwarding characteristics based on patterns
– Allow incoming raw, Telnet, and SSL/TLS (secure-socket) connections
 Serial data communication over UDP, also known as udpserial, can automatically perform the
following functions:
– Digi Connect products can automatically send serial data to one or more devices or systems
on the network using UDP sockets. Options for sending data include whether specific data
is on the serial line, a specific time period has elapsed, or after the specified number of
bytes has been received on the serial port.
– Control forwarding characteristics based on patterns.
– Support incoming datagrams from multiple destinations.
– Support outgoing datagrams sent to multiple destinations.
 TCP/UDP forwarding characteristics.
 Extended communication control on TCP/UDP data paths.
– Timeout
– Hangup
– User-configurable Socket ID string (text string identifier on autoconnect only)
Dynamic Host Configuration Protocol (DHCP)
Dynamic Host Configuration Protocol (DHCP) can be used to automatically assign IP addresses,
deliver TCP/IP stack configuration parameters such as the subnet mask and default router, and
provide other configuration information. For further details, see "Alternate methods for assigning an
IP address.” on page 39.
