Two conditions must be met for the alert_enable command to work:
•
A modem dial-out string must be entered from the system console.
•
Remote access to the RCM modem port must be enabled with the enable
command.
If the alert_enable command is entered when remote access is disabled, the
following message is displayed:
*** error ***
disable
The disable command disables remote access to the RCM modem port. It also
disables RCM dial-out.
RCM>disable
When the modem is disabled, it remains disabled until the enable command is
issued. If a modem connection is in progress, entering the disable command
terminates it.
NOTE: If the modem has been disabled from the RCM switchpack on the
motherboard, the enable command does not work. To enable the modem, reset the
switch 2 (MODEM OFF) on the switchpack to OFF (enabled).See Section 6.5 for
information on the switchpack.
enable
The enable command enables remote access to the RCM modem port. It can take up
to 10 seconds for the enable command to be executed.
RCM>enable
When the modem is enabled, it remains enabled until the disable command is
issued.
