7.5.1 Direct Modem Access
To allow for advanced trouble shooting of the communications, it is possible to access the modem
directly via the Control Module from a laptop computer.
Log in to the repeater, either with RMC, or with a terminal emulation program, such as
HyperTerminal™. When the login is completed, select Terminal Mode, this will give access to the
repeater command prompt in the same way as with HyperTerminal.
When the repeater prompt is accessible, type in the command
ACCESS MODEM <Enter>.
When typing ACCESS MODEM, the controller will send all the characters that are typed directly out
to the modem port. All characters replied back from the modem will go directly to the LMT port and
back to the computer.
To abort an ACCESS MODEM session, press three ‘-‘ in a row (all three within one second) to come
back to the repeater command prompt.
Note! When accessing the modem port the modem might be configured with “echo off”, meaning
that the characters entered will not be echoed back to the screen. In order to enable “echo”, press
Enter.
Type
ATE1 <enter>
(invisible)
The modem replies with
OK
indicating that the echo is enabled. All characters entered will now be echoed back to the terminal
program.
7.5.2 Trace Modem
For troubleshooting purposes it is possible to trace the actual progress of initializing the modem. This
trace is useful when having problems with the modem initialization.
