Supported basic network services and their default network port numbers
In Digi devices that have multiple serial ports, the network port number defaults for various services
are set based on the following formula:
base network port number + serial port number
The default base assumed is 2000. For example, the Telnet Passthrough service is set to network
port 2001 for serial port 1, 2002 for serial port 2, 2003 for serial port 3, etc.
If a network port is changed for a particular service, that is the only network port number that
changes. That change does not carry over to the other network ports. For example, if the network
port number for Telnet Passthrough is changed from 2001 to 3001, that does not mean that the other
network ports will change to 3002, 3003, etc.
There are two types of network services available:
 Basic services, which are accessed by connecting to a particular well-known network port.
 Passthrough services, in which a particular serial port is set up for a particular type of service.
To use the service, users must both use the correct protocol and specify the correct network port.
For example, assuming default service ports and using a Linux host, here is how a user would
access the SSH and Telnet passthrough services:
#> ssh -l fred digi16 -p 2501
#> telnet digi16 2101
