Introduction
Serial data communication over TCP and UDP
Digi devices 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 size, time, and pattern
– Allow incoming raw, Telnet, and SSL/TLS (secure-socket) connections
– Support RFC 2217, an extension of the Telnet protocol
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 size, time, and 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)
