Async Gateway Troubleshooting Strategies

Novell Confidential Manual (99a) 21 December 2004
Š Send a test message to check links and connections to certain domains. For more information,
see
“Testing the Async Gateway” on page 42 .
Creating a Modem Initialization String
If previous troubleshooting efforts were unsuccessful, the modem initialization string you have
used from the modem database might not be working. It might be necessary for you to create a new
modem initialization string to check this possibility.
You need to know what to include in a new initialization string. See the manufacturer’s modem
operation manual under index entries such as “initialization string,” “init string,” or “AT string,”
or contact the modem manufacturer for more information about the initialization string.
The initialization string should include characters for the following:
Š Enable verbal result codes
Š Turn command echo off
Š Track data carrier
Š Return CONNECT messages
Š Drop carrier and reset modem when DTR drops
Š Enable error correction
Š Enable CTS/RTS
Š Set modem to fixed DTE speed
For complete instructions, see “Creating a Modem Initialization String” on page 110 .
Using Aioterm.nlm to Troubleshoot the NetWare Async Gateway
Aioterm.nlm, available from Novell Support (http://support.novell.com) , can provide some data
about the modem intialization string that you might find helpful in troubleshooting.
You should download a file called aiotrm.exe, which is a self-extracting, compressed file including
the aioterm.nlm.
Load aioterm as you would any NLM. It displays the driver (or hardware) type, board number, and
ports supported. After the initial loading sequence, the Acquired Port Test Menu is displayed.
Follow these steps to obtain modem initialization string information in aioterm.nlm:
1
From the Acquired Port Test Menu, select Really Dumb Terminal Mode to display the
following prompt:
Any keyboard activity will be written to the port, but not echoed to the
screen.
The screen shows only characters received from the port (if you don’t see anything, try typing
ATE1
).
2
Type any character on the keyboard to activate the Really Dumb Terminal communications
program.
The program communicates with the modem and has it send its initialization string. If the
communication is working, the screen displays information something like this:
