VxWorks shell

Introduction
The VxWorks shell is used for performing basic administrative and management
tasks, the most important of which is loadware upgrade. You can access the
VxWorks shell through a serial connection from a PC or a telnet connection.
The shell is protected from unauthorized access by a username and password.
This password is common across FTP, telnet, and the serial port. If the shell is
idle for a period of time, the shell is logged off, and the password and username
must be reentered to gain access. This time-out defaults to 10 minutes, but it can
be set to any value between 30 and 4095 seconds (1 hour 8 minutes 15 seconds)
using the shell function shellTimeoutSet n, where n is the desired time-out in
seconds. The current value of the shell time-out in seconds is returned by the
shell function shellTimeoutGet:
-> shellTimeoutSet 600
-> shellTimeoutGet
value = 600 = 0x258
The shell time-out is stored in NVRAM, so changes are maintained across a
restart.
Note: Once the shell username and password have been successfully entered,
the user has complete access to all the VxWorks commands. Incorrect usage of
some shell commands causes the voice processing (VP) services loadware to
restart, and may change operational behavior.
To exit from the shell and return to the logon: prompt at any time, type the
command logout.
For the procedure to upgrade the loadware for the Media Card, see "Application
loadware upgrade for Media Card" on page 22.
