5.

Select the letter that corresponds to the model you
installed, select NOT INSTALLED if you have no
ISA-bus RocketModems in the system, or select X to
exit the diagnostic.
If you select an ISA-bus model, a list of valid I/O
addresses (A through K) displays:
a.

Select the letter for the I/O address you used
when installing the card. A list of valid IRQ
interrupts displays.

b.

Select the letter for the IRQ you used when
installing the card.

Note: Some drivers require an IRQ. If this is a new

installation, the correct entry will be I: NO
IRQ
.

c.

The diagnostic program loops back to Step 5.

d.

If you have more than one ISA RocketModem
installed, repeat this step until you have entered
the information for all cards. When you are
done, select NOT INSTALLED to exit this loop.

Note: Only the first card requires that the I/O

address entered in Step 5a matches the
physical DIP switch setting. For each
subsequent card, select any unused I/O
address.

The list of I/O and IRQ parameters you entered
displays.

6.

If the list is correct, press Y. If the information is not
correct, press N to restart the diagnostic.
The diagnostic resets and reintializes all modems. If
your model uses downloadable firmware, the
diagnostic also queries the firmware load status. If
the firmware has not been loaded, it is downloaded
automatically. If the firmware has been loaded, you
are asked to select Y to reload the firmware or N to
continue without reloading the firmware.

7.

After initialization completes, an option box displays
at the bottom of the screen:
– D to run the Diagnostic
– T for Terminal Mode at 9600 baud
– M for Terminal Mode at maximum baud
– Q to QUIT

8.

Press D to test the serial I/O and IRQ. (The T and M
options are discussed under Terminal Mode, below.)
The diagnostic tests each RocketModem card’s serial
I/O, IRQ, and telephone type, and displays the
results.

9.

Press any key to continue. If you have more than one
card installed, the diagnostic repeats until all cards
have been tested.

10. Press any key to continue. The diagnostic displays a

summary of the test results.

11. Press any key to continue.

The diagnostic resets all modems and reinitializes
all RocketModem boards.

12. Press Y to restart the diagnostic at Step 3 (for

example, to enter Terminal Mode), or N to quit.
If you select N, remove the diagnostic diskette from
the drive, then press the spacebar or Enter key to
boot the system. Do not use the CTRL-ALT-DEL
reboot command.
Use of this command may result
in CMOS errors on some systems.

Note: The Terminal Mode option is used to test modems

by dialing out using AT commands. For an
example of how to use this option, see
Terminal
Mode

, later in this Installation Card.

Troubleshooting

If an ISA-bus modem card fails to initialize, check to
make sure you have selected the correct I/O address and
IRQ. If that does not solve the problem, try removing the
card and reseating it in another slot.

If you have tried any “short cuts” in running the
diagnostic, try rebooting your system from the floppy.
The diagnostic WILL NOT WORK in a “DOS over
Windows” session.

Terminal Mode

If you select either the T or M Terminal Mode option
while running the diagnostic, the diagnostic starts a
simple terminal emulation program. The T option
selects terminal mode at 9600 baud, while the M option
selects terminal mode at the maximum baud rate
supported by your RocketModem model.
1.

If there is more than one RocketModem installed,
you are asked to select a card. Do so.

2.

A numbered menu listing the ports on the selected
card displays. You may also press H for help with AT
commands, R to reset a single modem, T to reset all
modems on the selected board, or X to exit.

3.

Enter a port number to select a modem. The
Terminal Mode screen displays.

4.

Type AT commands to communicate with the
modem.

5.

When you are done, press Esc to return to Step 2.

For example, follow these steps to test two modem ports.
This example requires that phone lines be connected to
both Ports 1 and 2.

1.

Select Port 1.

2.

Enter AT&F0 to initialize the modem to factory
default parameters.

3.

Enter ATS0=1 to direct the modem to answer the
phone on the first ring.

4.

Press Esc to return to the port menu.

5.

Select Port 2.

6.

Enter AT&F0 to initialize the second modem.

7.

Enter ATDxxx xxxx (where xxx xxxx is the phone
number of the line connected to the first modem).
Watch and wait. The Port 2 modem should dial the
Port 1 modem and you should eventually see the
CONNECT message.

8.

Press Esc.

9.

Select Port 1. You should see RING and CONNECT
messages.

10. Any keys you press while looking at Port 1 display

when you look at Port 2. Likewise, any keys you
press while looking at Port 2 display when you
return to the Port 1 display.

11. To exit, on either of the ports enter the escape

sequence +++. This enables you to enter ATH to
hang up, or any other valid AT command string.
If you do not hang up, you can return to the still-
active connection by entering ATO.

12. To exit terminal mode and return to the port menu,

press Esc.
