Operating the System Remotely C-5
C.1.2 Entering and Leaving Command Mode
Use the default escape sequence to enter RCM command mode for the first time.
You can enter RCM command mode from the SRM console level, the operating
system level, or an application. The RCM quit command reconnects the
terminal to the system console port.
Example C-2 Entering and Leaving RCM Command Mode
^]^]rcm ➊
RCM>
RCM> quit
➋
Focus returned to COM port
Entering the RCM Firmware Console
To enter the RCM firmware console, enter the RCM escape sequence. See
➊ in
Example C-2 for the default sequence.
The escape sequence is not echoed on the terminal or sent to the system. Once in the
RCM firmware console, the user is in RCM command mode and can enter RCM
console commands.
Leaving Command Mode
To leave RCM command mode and reconnect to the system console port, enter the
quit command, then press Return to get a prompt from the operating system or
system console. (See
➋).
