Table 4-3 RMC Troubleshooting Tips

Symptom
You cannot enter the
RMC from the modem.
The local terminal
cannot communicate
with the RMC correctly.
RMC will not answer
when the modem is
called.
After the system is
powered up, the
COM1 port seems to
hang or you seem to
be unable to execute
RMC commands.
New escape sequence
is forgotten.
During a remote
connection, the user
sees a "+++" string on
the screen.
The message
"unknown command"
is displayed when the
user enters a carriage
return by itself.
Possible Cause
The RMC may be in soft bypass
or firm bypass mode.
System and terminal baud rates
do not match.
Modem cables may be
incorrectly installed.
RMC remote access is disabled
or the modem was power cycled
since last being initialized.
The modem is not configured
correctly.
On power-up, RMC defers
initializing the modem for 30
seconds to allow the modem to
complete its internal diagnostics
and initializations.
There is a normal delay while
the RMC completes the
system power-on sequence.
The modem is confirming
whether the modem has
really lost carrier.
The terminal or terminal
emulator is including a line
feed character with the
carriage return.

Suggested Solution
Issue the show com1_mode command
from SRM and change the setting if
necessary. If in soft bypass mode, you
can disconnect the modem session and
reconnect it.
Set the baud rates for the system and
terminal to be the same. For first-time
setup, suspect the console terminal, since
the RMC and system default baud is
9600.
Check modem phone lines and
connections.
From the local serial terminal or VGA
monitor, enter the set password and set
init commands, and then enter the enable
remote command..
Modify the modem initialization string
according to your modem documentation.
Wait 30 seconds after powering up the
system and RMC before attempting to
dial in.
Wait about 40 seconds.
RMC console must be reset to factory
defaults.
This is normal behavior.
Change the terminal or terminal
emulator setting so that "new line" is
not selected.
