C-4 AlphaServer 4000/4100 Service Manual
Dialing In to the RCM Modem Port
1. Dial the modem connected to the server control module. The RCM answers the
call and after a few seconds prompts for a password with a “#” character.
2. Enter the password that was loaded using the setpass command. The user has
three tries to correctly enter the password. On the third unsuccessful attempt,
the connection is terminated, and as a security precaution, the modem is not
answered again for 5 minutes.
On successful entry of the password, the RCM banner message “RCM V1.0” is
displayed, and the user is connected to the system COM1 port. At this point the
local terminal keyboard is disabled except for entering the RCM console
firmware. The local terminal displays all the terminal traffic going out to the
modem.
3. To connect to the RCM firmware console, type the RCM escape sequence.
Refer to Example C-1 for an example of the modem dial-in procedure.

RCM> RCM prompt is displayed. Commands to control and

Terminating a Modem Session
Terminate the modem session by executing a hangup command from the RCM
console firmware. This will cleanly terminate the modem connection.
If the modem connection is terminated without using the hangup command, or if the
line is dropped due to phone line problems, the RCM will detect carrier loss and
initiate an internal hangup command. This process can take a minute or more, and
the local terminal will be locked out until the auto hangup process completes.
If the modem link is idle for more than 20 minutes, the RCM initiates an auto
hangup.
