Terminal Server Modem control must be enabled. Using modems on ports without
modem control enabled will lead to security problems.
The Terminal Server Autobaud feature should be enabled only when required.
11.6 Entering Commands at the Boot
Prompt
If the Boot> prompt appears on the serial console instead of the Local> prompt, one of two
things may be wrong. Either the Terminal Server does not have enough information to boot,
or the network or flash boot has failed. If pressing the
Return
key does not display a
prompt, press any other key. The Boot> prompt should appear.
If the Terminal Server does not have enough information to boot, or the network or flash
boot has failed, it will print a message to the console and wait ten seconds for serial port
activity. If it detects serial port activity, it will continue booting provided the flash is good.
However, if the user presses a key during that time period, the Terminal Server will display
the Boot> prompt.
Note:
If you see the message “Will attempt another download in x minutes,”
press any key for the Boot> prompt.
A series of commands called Boot Configuration Program (BCP) commands can be entered
at the Boot> prompt to configure the Terminal Server. These commands are a subset of the
entire Terminal Server command set. For example, a typical TCP/IP configuration might
use the following commands:
Figure 11-1:
BCP Command Examples
These commands set the Server’s address, the software loadfile, and the loadhost’s IP
address (as well as that of a backup loadhost). The server then reboots using the
Flash
command and will attempt to load the file LES.SYS from the host at 192.0.1.188.
Flush NVR
This command is used to restore the Terminal
Server’s non-volatile RAM to its factory de-
fault settings. It will reset everything that is
configurable on the server, including the unit’s
IP address.
