Network Services Associated with Specific Serial Ports
Network service connections associated with specific serial ports include:
Network Services Associated with Serial Ports in General
The Digi Connect WAN does not support the following features: RealPort, Modem
emulation, and rsh. Network service connections associated with serial ports in general
include:
Network Services Associated with the Command-Line Interface (CLI)
Network service connections associated with the Command-Line Interface (CLI) include:
Reverse Telnet: A telnet connection is made to a Digi Connect device, in which
data is passed transparently between the telnet connection and a named serial
port.
Reverse raw socket: A raw TCP socket connection is made to a Digi Connect
device, in which data is passed transparently between the socket and a named
serial port.
Reverse TLS socket: An encrypted raw TCP socket is made to a Digi Connect
device, in which data is passed transparently to and from a named serial port.
LPD: A TCP connection is made to a named serial port, in which the Digi
Connect device interprets the LPD protocol and sends a print job out of the
serial port. (Not supported in Digi Connect WAN.)
Modem emulation, also known as Pseudo-modem (pmodem) (not supported in
Digi Connect WAN): A TCP connection is made to a named serial port, and the
connection will be “interpreted” as an incoming call to the pseudo-modem.
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 Connect 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.
Telnet: A user can Telnet directly to a Digi Connect device’s CLI.
