Comtrol RM ISA V.34 - Manual (Page 4)

Hardware Installation Card 4 of 7
installed, repeat this step until you have entered
the information for all the 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
appears.
6. If the list is correct, press Y. If the information is not
correct, press N to restart the diagnostic.
The diagnostic resets and re-initializes all modems.
7. After initialization completes, an option box appears 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 the Terminal Mode
section.) 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 re-initializes all
RocketModem boards.
12. Press Y to restart the diagnostic at Step 3 (for example,
to enter the Terminal Mode), or N to quit.
If you select N, remove the diagnostic diskette from the
drive, then press the space bar 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: You use the Terminal Mode option to test modems by
dialing out using AT commands. For an example of
how to use this option, see the Terminal Mode section.
Troubleshooting
If an ISA-bus modem card fails to initialize, check to make
sure that you have selected the correct I/O address and
IRQ. If that does not solve the problem, try removing the
card and reseating it into 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 a
terminal mode at 9600 baud, while the M option selects a
terminal mode at the maximum baud rate supported by
your RocketModem model.
1.
If there are more than one RocketModems installed,
you are asked to select a card. Select a card.
2. A numbered menu listing the ports on the selected card
appears. 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 appears.
4. Type AT commands to communicate with the modem.
5. When you are done, press the Esc key to return to Step
2.
For example, follow these steps to test two modem ports.
This example requires that you connect phone lines to both
Ports 1 and 2.
1. Select Port 1.
2. Enter AT&F0 to initialize the modem to the factory
default parameters.
3. Enter ATS0=1 to direct the modem to answer the phone
on the first ring.
4. Press the Esc key to return to the port menu.
5. Select Port 2.
6. Enter AT&F0 to initialize the second modem.
7. Enter ATDTxxx 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 the Esc key.
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 the Esc key.
