Troubleshooting
If you are still unable to resolve the problem, try the following:
• Check to make sure that you are using the correct cables, and that the cables are connected properly.
• If using ISA boards, check to make sure the DIP switches are set to the desired addresses.
• Reseat the board in the expansion slot, or try moving the board to another slot of the same bus type.
• Make sure that the expansion slot screw is replaced after inserting or moving the board.
• Use RCKTTERM to determine whether the ports are functioning properly.
If you are still unable to resolve the problem, contact Technical Support . When you contact Comtrol, please
have the following information available:
• NetWare Connect or MPR revision number
• SPACK (Support Pack) revision number
• AIORCKT.NLM version number
To determine the AIORCKT.NLM version number:
1. At the server console prompt, enter:
modules aiorckt.nlm
2. If necessary, scroll down the list until the aiorckt.nlm version number displays.
To generate a system Configuration Report:
1. At the server console prompt, enter load techwalk
2. This generates a Configuration Report (techwalk.out) that is stored in the /etc directory. This report
contains much useful and valuable information and may be requested by Comtrol Technical Support.
RCKTTERM Overview
RCKTTERM is a simple AIO application similar to the Novell AIOTERM.NLM, which has been modified to
work with the RocketModem/Port boards and the AIORCKT.NLM driver. RCKTTERM supports up to four
RocketModem/Port boards with up to 32 ports on each board. RCKTTERM displays information on the
currently loaded AIORCKT driver and the boards.
RCKTTERM has the following capabilities:
• You can specify the board and port you want to test, review, or reconfigure.
• View the port’s capabilities and current configuration.
• Reconfigure ports.
• Perform simple data transfers.
• Send data out to a RocketPort port that has a loopback plug connected to verify that the port is functioning
properly when it is echoes back to the screen.
• Connect two ports together with a NULL MODEM cable, which allows data to be sent out one of the ports
from the keyboard. Then you can select the receiving port and it can be verified on the screen.
• Test modem operations.
Testing Modem Operations
You can use RCKTTERM to test modem operations by selecting a port and issuing AT’ modem commands.
Responses can be verified as they are echo back and display on the screen.
If two modems are connected to phone lines or a line simulator, the dial command can be issued from the first
modem and the second modem should answer the call. The modem must be configured with the number of
rings to answer using the ATS0= command and negotiate a connection. Selecting the port for the second
modem you should be able to see the RINGs displayed on the screen. Once this connection has been
established, any data entered on the keyboard for one port displays on the screen when looking at the second
port. The connection can be terminated by entering the +++ escape sequence on one of the ports. This allows
that modem to recognize AT’ commands again. At this point if the ATH command is issued to the modem, it
hangs up and the connection terminates.
