disables use of the Digi Device Discovery utility to locate the device,
either on its own or as part of running the Digi Device Setup Wizard.

default.

servers or terminal servers.
A virtual connection to serial devices, no matter where they reside on
the network.

instead of Public Switched Telephone Network (PSTN). Telnet
processing can be enabled or disabled on the incoming and outgoing
modem-emulation connections. The pmodem service is for
connecting to whatever serial port will answer.

interface through Rsh.

this command.
If disabled, SNMP services such as traps and device information are
not used.
