Configuring Remote Dial-In Access
Chapter 13 121
Introduction
The Digi CM unit supports dial-in connections from remote sites for out-of-
band access. In this configuration, the Digi CM unit has serial ports configured
for external modems and waits for dial-in connections from remote sites. If you
dial-in using a terminal application, the Digi CM unit accepts the connection
and displays a menu of available serials ports. In a dial-in terminal server
mode, the Digi CM unit makes a TCP connection with either a Telnet or SSH
client to a pre-defined server. RawTCP is also an option for dial-in users.
For more information on the different types of Host mode configuration, see
"Host Mode Configuration" on page 52.
