Network/Serial Clients - Digi TS 8 MEI User Manual

Network/serial clients

A network/serial client connection is one in which a Digi device initiates a network connection or
opens a serial port for communication. There are several categories of network/serial client
connections:



Autoconnect behavior client connections
In client connections that involve autoconnect behaviors, a Digi device initiates a network
connection based on timing, serial activity, or serial modem signals. Autoconnect-related client
connections include:




Command-line interface (CLI)-based client connections
Command-line interface based client connections are available for use once a user has established
a session with the Digi device's CLI. CLI-based client connections include:



Modem emulation (pseudo-modem) client connections
When a port is in the modem-emulation or pseudo-modem mode, it can initiate network
connections based on AT command strings received on the serial port.The AT commands for
modem emulation are documented in the Digi Connect Family Command Reference.
