Supported connections and data paths in Digi devices
23
Network services associated with serial ports in general
RealPort: A single TCP connection manages (potentially) multiple serial ports.
Modem emulation, also known as pseudo-modem (pool): A TCP connection to the
“pool” port is interpreted as an incoming call to an available pseudo-modem in the
“pool” of available port numbers.
rsh: Digi devices support a limited implementation of the Remote shell (rsh) protocol, in
that a single service listens to connections and allows a command to be executed. Only
one class of commands is allowed: a single integer that specifies which serial port to
connect to. Otherwise, the resulting connection is somewhat similar to a reverse telnet or
reverse socket connection.
DialServ: Connecting a DialServ device to the serial port. DialServ simulates a public
switched telephone network (PSTN) to a modem and forwards the data to the serial port.
The Digi device sends and receives the data over an IP network.
Network services associated with the command-line interface
Telnet: A user can Telnet directly to a Digi device’s command-line interface.
rlogin: A user can perform a remote login (rlogin) to a Digi device’s command-line
interface.
