Table 6–5 RMC Troubleshooting (Continued)
Symptom
New escape sequence is
forgotten.
During a remote
connection, you see a
"+++" string on the
screen.

display power on or power

external RMC/COM1 port.

Possible Cause
The modem is confirming
whether the modem has really
lost carrier. This is normal
behavior.
The display of these messages
varies with the system state and
the setting of com1_mode.
Suggested Solution
RMC console must be reset
to factory defaults.
Set com1_mode to through
mode or snoop mode.
