On AC power-up, RMC
defers initializing the mo-
dem for 30 seconds to allow
the modem to complete its
internal diagnostics and
initializations.
Wait 30 seconds after
powering up the system
and RMC before at-
tempting to dial in.
After the system is
powered up, the COM1
port seems to hang or
you seem to be unable
to execute RMC com-
mands.
There is a normal delay
while the RMC completes
the system power-on se-
quence.
Wait about 40 seconds.
New escape sequence
is forgotten.
RMC console must be
reset to factory defaults.
During a remote con-
nection, you see a
“+++” string on the
screen.
The modem is confirming
whether the modem has
really lost carrier. This is
normal behavior.
The message “un-
known command” is
displayed when you
enter a carriage return
by itself.
The terminal or terminal
emulator is including a
line feed character with
the carriage return.
Change the terminal or
terminal emulator set-
ting so that “new line” is
not selected.
